摘要: Abstract The degradation and glass transition temperatures of a series methyl methacrylate (MMA)-ethyl α-hydroxymethylacrylate (EHMA) copolymers have been studied by t.g.a./i.r. d.s.c. Thermal yielded intramolecular lactone intermolecular crosslinking formation, with concurrent loss ethanol and/or methanol involving adjacent or near-neighbour EHMA MMA units. Glass transitions analysed as function sequence distribution their values compared to the theoretical ones derived using Johnston's equation. partially degraded increased consequence above mentioned formation.
