Abstract

Results of an experimental study are presented in which linear polyester polyurethanes were prepared, crosslinked and tested. It is shown that high temperature crosslinking of two phase materials can reduce their Young's modulus, thermal stability and recovery rate. These data may well have relevance to the time dependent behavior of network urethanes prepared by reactive molding where crosslinking is induced at high temperatures. Experimental data are plotted and evaluated.
