Abstract
AbstractA number of polymers belonging to poly(olefin oxide) and poly(olefin sulfide) series have been prepared and their glass transformation temperatures determined by dilatometry and differential thermal analysis. In the poly(olefin oxide) series, the Tg remained practically unchanged as the length of the pendent alkyl group was increased from methyl to n‐hexyl. However, a 20°C decrease in Tg was observed when the pendent group was changed from ethoxymethyl to n‐hexoxymethyl. In the poly‐(olefin sulfide) series, the Tg value decreased as the pendent alkyl group changes from methyl to ethyl. Replacement of ether oxygen in the polymer main chain by sulfide sulfur increased the Tg value. In some polymers, first‐order transitions were observed, but their significance has not been assessed.
