Research paper thumbnail of Copolymerization of methyl- and buthylmethacrylate with electron-donor N-(2-hydroxyethyl)carbazolyl methacrylate and electron-acceptor (β-hydroxyethyl)-3,5-dinitrobenzoyl methacrylate

Polymer Bulletin, 1985

The reactivity ratios of the binary systems were computed by using the Kelen-TiJd6s method. The azeothropic compositions were established according to the respective copolymerization diagrams.

Introduction of the electro-donor (or electro-acceptor) group into a methacrylate triad allways increases the T contribution of the homopolymer g triad, whilst the introduction of a methacrylate group into the electro-donor (acceptor) triad decreases the respective T contribution. g
