The thermoplastic polyester-polyurethane elastomers were synthesized from poly-hexamethylene 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.
