摘要

A series of stable waterborne polysiloxaneurethane (WPSUR) dispersions were prepared using amino-terminated polydimethylsiloxane (NS)

dimethylolpropionic acid (DMPA)

castor oil

polypropylene glycol and toluene diisocyanate. Meanwhile

NS with different molecular weights was synthesized and used as the soft co-segment. Effects of types and contents of soft co-segments as well as chain extenders on the thermal degradation and stability for WPSUR films were examined. Results reveal that WPSUR films exhibit excellent water resistance and mechanical properties as compared with pure polyurethane (PU) films

and the NS soft co-segment possesses a remarkable effect on the second stage (stage II)

while the content of the hard segment is propitious to the initial stage (stage I). Moreover

the highest temperature of stage II (T2m) for WPSUR films using NS as soft co-segment is 413οC

approximately being 30οC higher than that of those typical PUs using HDA and APDMS as the chain extenders

respectively.
