Waterborne hyperbranched alkyd-acrylic resin obtained by miniemulsion polymerization

Abstract Four waterborne hyperbranched alkyd-acrylic resins (HBRAA) were synthesized by miniemulsion polymerization from a hyperbranched alkyd resin (HBR), methyl methacrylate (MMA), butyl acrylate (BA) and acrylic acid (AA), by using benzoyl peroxide (BPO) and ammonium persulfate (AP) as initiators. The reaction between HBR and acrylic monomers was evidenced by differential scanning calorimetric (DSC), nuclear magnetic resonance (NMR) and gel permeation chromatography (GPC). The conversion percentage, glass transition temperature (Tg), content of acrylic polymer (determined by soxhlet extraction) and molecular weight increased with the content of acrylic monomers used in the synthesis. The main structure formed during the synthesis was the HBRAA. The analysis by dynamic light scattering (DLS) showed that the particle size distribution of HBRAA2, HBRAA3 and HBRAA4 resins were mainly monomodal. The film properties (gloss, flexibility, adhesion and drying time) of the HBRAA were good

Audiovisuell Perception och immersion : En kvalitativ undersökning av en multimodal installation i förhållande till rummet

Syftet med denna forskning genom design och kvalitativa undersökning är att skapa en audiovisuell installation vilket mäts av en fokusgrupp för att se om fenomenet Immersion uppnås hos informanterna. Det är informanternas kollektiva och subjektiva upplevelse av installationen som ligger till grund för studiens resultat och berör frågor inom det audiovisuella området. Installationen undersöks i förhållande till rummet den tar plats i som en viktigt påverkande aspekt. Studien ska ses på som ett förslag för hur fenomenet Immersion kan uppnås genom audiovisuella verktyg. Alltså är detta en studie som inte försöker nå en absolut sanning genom undersökningen utan olika resultat kan nås även om genomförandet av installationen skulle försökas återskapas. Resultaten tyder på att Installationen kändes Immersiv och nåddes genom projektionskonstformen och spatialt 3D ljud. Samt att andra aspekter och egenskaper som att installationens fysiska form, vilket bestod av genomskinligt tyg som omringade informanterna, påverkade deras Immersion positivt genom att avskärma deras perception. Det presenteras även andra aspekter och egenskaper som påverkade informanternas upplevelse av Immersion positivt men även resultat som påverkade upplevelsen negativt, vilket är lika viktigt för vidare forskning och som bidrag till det kunskapsområdet. Styrkan i undersökningen är presentationen av installationens genomförande men framförallt resultatet som bidrar med förståelse och perspektiv till ett svårformulerat intresseområde. Svagheten ligger i och med att fokusgruppdiskussioner och kvalitativa underökningar inte går att generaliseras, samt så är validiteten svår att styrka. Ytterligare en svaghet är att bara en fokusgrupp användes för studiens undersökning vilket gör det svårt att säkerställa resultatets giltighet

High Solids Waterborne Hybrid Systems: Effect of Surfactant Concentration and pH on Droplet Size and Morphology

Hybrid systems have been made by taking an acrylic latex dispersion and slowly dropping an alkyd resin into the dispersion while stirring to achieve a solid content of 75–80%. The particle size distributions of alkyd droplets were studied with a laser diffraction instrument and the structure of the hybrid system in the liquid state has been studied by light microscopy. The hybrid system was defined as a suspoemulsion, which are mixtures of suspensions and emulsions. In the present hybrid system the alkyd is present as an oil-in-water (O/W) emulsion and the suspension is represented by the acrylic latex. When the way of adding surfactant and the added amount of surfactant were changed, it was found that addition of surfactant to the system decreases alkyd droplet size more effectively if the surfactant is present in the acrylic latex. If the surfactant was added to the latex prior to the addition of alkyd it resulted in the formation of O/W emulsions. On the other hand, in the case of addition of surfactant to the alkyd before dropping it into the latex, water-in-oil-in-water (W/O/W) double emulsions in respect of the alkyd were observed, and in order to obtain the same decrease in alkyd droplet size as in the experiments where surfactant was added to the latex, a higher surfactant concentration was needed

Morphologies and droplet sizes of alkyd-acrylic hybrids with high solids content

Alkyd-acrylic hybrids having final solids content of 75-80% were prepared by dropping alkyd resin into an acrylic dispersion. The resulting suspo emulsion structures and the alkyd droplet sizes in the hybrids were dependent on the preparation procedure as well as the interfacial tension between the two liquid phases, sigma(12), the shear rate, gamma, the latex/alkyd ratio and the viscosity ratio, p, between the viscosity of the dispersed phase. eta(d), and the viscosity of the matrix, eta(m). sigma(12) was varied by changing the surfactant concentration and pH of the hybrids, eta(d) was varied by changing the viscosity of the alkyd phase but was also affected by variations in the pH, and finally the shear stress was varied by varying the solids content and the amount of latex in the hybrid systems. Parameters that effected the ratio, p, were also studied separately and in combination. and by varying parameters such as the presence of latex particles, alkyd viscosity and solids content, the effect of p on the alkyd droplet size was determined. Different liquid structures were obtained depending on how the surfactant was added to the system. When surfactant was added to the latex prior to the addition of the alkyd, an O/W emulsion was formed. However, if the surfactant was added to the alkyd prior to the addition of the alkyd to the latex, a multi-emulsion (W/O/W) of alkyd was formed, which was also observed when the hybrids were prepared at a high pH. The structures obtained were stable over time and remained unchanged even after ageing for 1 year at room temperature. (C) 2004 Published by Elsevier B.V

Suspension structures and film morphologies of high-solids acrylic-alkyd hybrid binders

The development of new binders used for coatings has traditionally been driven by a combination of the need for technical improvements and increased environmental awareness, together with stricter legislation regarding VOC (volatile organic compound) emissions. One interesting way to achieve new types of binders is to combine already existing ones, thereby exploiting the positive properties of both. In the present study, a combination of an alkyd and an acrylic dispersion was used to produce a potential hybrid binder. The structures of the binders both in the liquid state and in films prepared from the hybrids were studied using several microscopy techniques. It was found that the preparation method of the hybrids affected the morphology to a large extent, and the structural information was also linked to the rheological behaviour of the hybrids as well as to the mechanical properties of the final binder films
