Patent ID: 8420746

Claim:
A biodegradable composition comprising: a polymer component including a first polymer of polybutylene-1,4-succinate (PBS); a cross-linking agent capable of producing a free radical to allow said polymer component to be subjected to a free radical cross-linking reaction in such a condition that said biodegradable composition has a melt index ranging from 1.5 to 3.0; and a grafting component selected from the group consisting of butyl acrylate (BA), vinyl acetate (VAc), and the combination thereof; wherein said cross-linking agent is a peroxide selected from the group consisting of dicumyl peroxide (DCP), benzoyl peroxide(BPO), 2,5-dimethyl-2,5-di(tert-butylperoxy) hexane, and 3,6,9-triethyl-3,6,9-trimethyl-1,4,7-triperoxonane.
