Summary

Tg studies on copolymers of methyl methacrylate and of butyl methacrylate with N-(2-hydroxyethyl) carbazolyl methacrylate as electro-donor and respective with methacryloyl-β-hydroxy-ethyl-3, 5-dinitrobenzoate as electro-acceptor comonomer have shown that the glass transition behaviour can only be explained by the effect of triad sequences. Introduction of the electro-donor (or electro-acceptor) group into a methacrylate triad allways increases the Tg contribution of the homopolymer triad, whilst the introduction of a methacrylate group into the electro-donor (acceptor) triad decreases the respective Tg contribution.
