BIODEGRABLE ALIPHATIC POLYESTER RESIN COMPOSITION AND METHOD FOR MAKING THEREOF

摘要

The mixture of 118.8g succinic acid and 118g butanediol was reacted with 0.03g tetrabutyltitanate as a catalyst at 200 deg.C for 90 min and than polycondensed with 0.4g dibutyltinoxide as a catalyst and 0.25g trimethylphosphate as a stabiliser followed by adding 10g polycaprolactam having a mol. wt. 40,000 at 245 deg. C for 5 hr to give a biodegradable aliphatic polyester.
