Abstract

Abstract: The thermoplastic polyester-polyurethane elastomers were synthesized from polyhexamethylene carbonate, polytetramethylene adipate, diphenyl methane-4,4′disocyanate and 1,4-butylene-glycol. Their glass transition temperature, mechanical property, hydrolytic stability and rheological property have been studied. The results show that the T_g, and the apparent viscosity of tlie polymer melt decreased vVith the increase of the polycarbonate content.The processability and hydrolytic stability of the elastomer were improved.

Key words: polycarbonate, polyester, polyurethane, thermoplastic elastomer, mechanicalproperty, hydrolytic stability
