摘要: Abstract As the temperature is progressively raised, alternating copolymer of vinyl acetate and crotonic acid degrades in two main stages: first (up to about 270°C), acetic lost through a lactonisation reaction between dissimilar chain units, accompanied by parallel involving decarboxylation some groups. At higher temperatures, further loss occurs, but degradation products are carbon dioxide, from decomposition γ-lactone rings, fragments lactonised backbone formed at lower temperatures. A variety minor volatile also second stage. Unlike poly(vinyl acetate), almost without residue 500°C.
