Production method of biodegradation characteristic polymer composition and biodegradation characteristic polymer composition

摘要

Poly- (hidorokishibuchirato) or that copolymer, the plasticizer and the nucleation medicine which are obtained from the renewable source, the flow aid and the thermal stabilizer are included, production method of the biodegradation characteristic polymer composition and the biodegradation characteristic polymer composition. Biopolymer already includes stage and the plasticizer where procurement (obtention) method, in the PHB or PHBV powder shell filler, was distilled and hydrogenated and, mixes 30% from the vegetable oil of natural source and the plasticizer approximately 2% which is based on the fatty acid of the animal and the plant beginning, the thermal stabilizer, nucleation medicine and stage and in order to promote the granule conversion which follows to that with incorporating the additive to in the PHB or PHBV which mix the flow aid matrix in melted state, it includes with the stage which pushes out the composition which is obtained at front stage.
