| Abstract: | A series of casting polyurethane elastomers were synthesized by using 3,3'-dimethyl-4,4'-biphenylene diisocyanate(TODI) with polytetramethylene ether glycol(PTMG),polycaprolactone polyol(PCL).The influence of different polymer polyols,chain extenders and hard segment content on heat resistance and mechanical properties of the elastomers was investigated.The results show that the heat resistance and mechanical properties of PCL system are better than those of PTMG system,the retention rate of tensile strengt... |
