Terminology of polymers and polymerization processes in dispersed systems (IUPAC Recommendations 2011)

A large group of industrially important polymerization processes is carried out in dispersed systems. These processes differ with respect to their physical nature, mechanism of particle formation, particle morphology, size, charge, types of interparticle interactions, and many other aspects. Polymer dispersions, and polymers derived from polymerization in dispersed systems, are used in diverse areas such as paints, adhesives, microelectronics, medicine, cosmetics, biotechnology, and others. Frequently, the same names are used for different processes and products or different names are used for the same processes and products. The document contains a list of recommended terms and definitions necessary for the unambiguous description of processes, products, parameters, and characteristic features relevant to polymers in dispersed systems

Atom transfer radical polymerization of methyl acrylate with molybdenum halides as catalysts in an ionic liquid

International audienceThe atom transfer radical polymerization of methyl acrylate in 1‐butyl‐3‐methylimidazolium hexafluorophosphate was studied with a molybdenum halide catalytic system. A combination of a bromine‐containing initiator (ethyl‐2‐bromopropionate) with a chloride‐containing catalyst [MoCl3(PMe3)3/MoCl4(PMe3)3] led to a controlled polymerization, and matrix‐assisted laser desorption/ionization time‐of‐flight analysis of the polymers indicated that the reversibly deactivated macromolecules contained both bromine and chloride end groups

Biodegradable polymer networks via triazolinedione-crosslinking of oleyl-functionalized poly(epsilon-caprolactone)

The formation of biodegradable polymer networks by the crosslinking of tailor-made poly(epsilon-caprolactone) (PCL) via the ultrafast 1,2,4-triazoline-3,5-dione (TAD) chemistry has been demonstrated. First, a series of alpha,omega-oleyl terminated PCL was prepared by a two-step, one-pot synthesis that was initiated by the coordination ring opening polymerization of epsilon-caprolactone, resulting in prepolymers bearing both an oleyl and hydroxyl end group, which were subsequently coupled by means of a diisocyanate. Network formation was performed via Alder-ene reaction of two different bifunctional triazolinediones (bisTADs) with the oleyl end groups. Different crosslinking parameters were studied in order to find the optimal conditions for the preparation of sufficiently strong polymer networks. Besides the determination of thermal and mechanical properties, as well as the susceptibility to hydrolytic degradation, of the obtained PCL-network, also the influence of the PCL molecular weight, nature of the TAD crosslinker and crosslinking stoichiometry were determined
