Abstract: | In the present study, the synthesis of bis(cyclic carbonate) from carbon dioxide and bisphenol A (or bisphenol S)-diglycidyl
ether was investigated using quaternary ammonium salts as catalyst. Among the salts tested, the one having a larger alkyl
group and more nucleophilic counter anion exhibited a better catalytic activity. Poly(hydroxyurethane)s were prepared by the
polyaddition reaction of bis(cyclic carbonate) and diamine. The poly(hydroxyurethane) has shown higher thermal stability than
conventional polyurethane, and is expected as novel reactive polyurethane. The miscibility of blends containing poly(hydroxyurethena)
and poly(styrene-co-acrylonitrile)(SAN) has been also studied by the optical clarity method and DSC. |
