• The Relationship between Chemorheology and the Degradation Behavior of Crosslinked Polyurethane Rubber

抄録

Chemorheology is the best means to elucidate the degradation mechanism of cross-linked polymer at its initial stage. Most of chemorheological research which have been carried out all this while are those related to the scission mechanism of main-chains. The paper deals with the scission mechanism of crosslink site of crosslinked polymers which case is very rare. Polyurethane vulcanizates are exposed in N² gas at high temperatures, 383, 393 and 403K, and in the solution of n-BuNH₂/DMSO at 298, 303 and 308K. Chemical relaxation curves thus obtained were found to be consistent with theoretical prediction by Tobolsky. The scission mechanism of cross-link sites of polyurethane vulcanizates was also studied by the swelling, GPC, and IR measurements.
