摘要：

Blends of a polyurethane with two different functionally reactive elastomers have been prepared by two different blending techniques. The thermal stability of the blends was studied to correlate the effect of blending technique on the degradation temperatures of the blends. The blending technique plays an important role in determining the thermal stability of the blends. For the same elastomer ratio, the preblended sample degraded at a lower temperature and the degradation temperatures for the preheated preblended samples were delayed. This may be due to the interchain crosslinking reaction between the two elastomers on heat treatment. (C) 2001 Elsevier Science Ltd. All rights reserved.
