Abstract New polymer brushes with an ester backbone and poly(methyl methacrylate) side chains are synthesized by polycondensation and polymerization methods. The initiating groups are sulfonyl chloride groups laterally attached to the polyester chain. PMMA side chains are grafted by the ATRP method according to the “grafting from” multicenter macroinitiator strategy. The conditions for the polymerization processes in a controlled mode are selected, and the ways of targeted regulation of the degree of polymerization of methacrylate side chains are determined. Using the synthesized copolymers self-supporting films are obtained, and their physical and mechanical properties are studied.

Grafting From

Abstract Graft copolymerization by conventional radical polymerization leads to poor control in molecular weight and quite often gel formation because of several side reactions. In this investigation, PMMA was grafted on poly(epichlorohydrine-co-ethylene oxide) (ECO) elastomer by using ‘grafting from’ technique via atom transfer radical polymerization (ATRP), a very recently developed method of controlled radical polymerization. The pendant —Cl group in ECO rubber was activated by using CuBr catalyst and thus macromolecular chain in ECO rubber acted as macroinitiator. Grafting of PMMA on ECO was confirmed by FT-IR and NMR analyses. DSC traces showed two Tgs in PMMA grafted ECO rubbers indicating microphase separation of hard and glassy PMMA microdomains in the flexible elastomeric ECO matrix. Interestingly, there was large increase in tensile strength and tension set in the ECO-grafted-PMMA materials.
