Traditional crosslinked polyester elastomers are inherently weak, and the strategy of increasing crosslink density to improve their mechanical properties makes them brittle materials. Biodegradable polyurethanes, although strong and elastic, do not fare well in dynamic environments due to the onset

## Abstract Polyester urethane networks are versatile polymer systems as it is possible to tailor their mechanical properties and their hydrolytic degradation profile. For biomedical applications, the biodegradability as well as the thermomechanical properties of the polymer networks during the cou
## SYNOPSIS Chlorinated polyethylene (CPE)-modified polyester prepolymers with NCO end groups were synthesized. The chain-extension reactions of the prepolymers with 3,3'-dichloro-4,4'diaminodiphenylmethane were studied by Fourier transform infrared spectrometry and found to change from second-ord
