Modification of epoxy resin by oligomaleimidohydroxyphenylene

The article is devoted to development and research of new film materials on the basis of epoxy pitches with the improved properties. The assessment of protective properties is defined by electrochemical methods of research, and also with physic-mechanical that gives the most complete idea of the corrosion processes proceeding under a paint and varnish film. Data of researches allowed to correct covering structure for separate scopes for the purpose of achievement of high extent of protection of metal surfaces

Polyimide use in photolithography process

Polyimides thanks to the unique properties such us thermal stability, good mechanical and electrical characteristic, resistance to high energy a wide temp erature range, excellent planarization popular in engineering and technology, particular in microelectronics. The production efficiency can be improved by providing photoresist properties to the polyimide materials using in microelectronics technology due to reduction of process steps and low bad production. Conversation is about, the creation of photosensitive pol-yimides negative and positive type containing reactive groups, which can by capable of being polymerized by UV-light with photo initiator. The main aim of this work increase the sensitivity, resolution and heat resistance of the material, on the base of a photosensitive polyimide composition. A new photosensitive polyimide composition based on polyamide acid solution in an organic solvent, tetramaleinamidoasid with the light-sensitive component. As show in the article, the possibility to create polymer cposs-linked structure which can explain solubility difference after UV-radiation exposure in the chemical natural of the compounds. The composition has shown good results in photosensitivity and other properties

Influence of fractional structure of the granulated nanofibrous carbon filler on electrophysical properties of epoxy composites

The effect of fractional structure of the granulated nanofiber carbon filler on the electrical properties of epoxy resin composites has been investigated in this article. The conductivity and permittivity of composite materials has been measured in the frequency range of 100 Hz – 1 MHz. It was shown that the grain-size distribution of the applied filler effects the electrical properties of epoxy resin / carbon nanofiber composites

Oligoaminoimidophenylene, effective modifier for melaminalkyd varnish

The present article deals with the development and study of new coatings based on industrially produced melamine-alkyd varnish of improved performance characteristics. It describes the synthesis of a dis-oligomeric amineimido modifier which is soluble in ethyl cellosolve and polar aprotic solvent, various formulations of varnish composition being also investigated. The physical-mechanical properties of coatings prepared from the compositions involved have been analyzed. Due to the formation of additional network structure, the introduction of the proposed modifier allows to increase the hardness of coatings, their impact and water resistance, as well as to improve adhesion while maintaining coating elasticity. The composition developed contributes to a significant increase in th e life of the coating for automobiles, buses, trolley buses, agricultural and other machinery and steel structures
