“…Polyurethanes, with soft and hard segments, were subjected to DTA and DSC, and fusion peaks and enthalpies of fusion were determined for the respective segments (138). DTA was applied to block copolymers from polydiethylene glycol adipate and poly-(o-bis [ß-hydroxyethoxy jphenylene adipate) and hexamethylenediisocyanate (358) and DSC used to examine p,p'diphenylmethane diisocyanate chain extended with butanediol (896). Copolymers of a-olefin-SCh, with even numbered «-olefines from Ce-Cig, were prepared and their melting temperatures were determined by DTA, DSC, and Kofler melt bar (67).…”
