DEGRADABLE RESIN COMPOSITION

摘要

The biodegradable resin composition consists of 5-99wt% thermoplastic resin, 0.1-95wt% degradable synthetic aliphatic polyester, 0-85.5wt% starch, and 0.1-20wt% autooxidizing agent. Thermoplastic resin is polyolefin resin, grafted copolymer of polyolefin resin and alpha, beta-unsaturated carboxylic acid, or a mixture of polyolefin resin and less than 50wt% ethylene-vinylacetate copolymer. Degradable synthetic aliphatic polyester is polycaprolactone. Starch is treated with silicone and titanium to substitute hydroxyl group with ether or ester. Autooxidizing agent is fatty acid or fatty acid ester.
