Degradation promoter for biodegradable resin, biodegradable resin composition and biodegradable resin molded body

摘要

Problem to be solved: to improve the biodegradation rate and the decomposition rate of biodegradable resin such as aliphatic polyester resin, aliphatic aromatic polyester resin and aliphatic oxycarboxylic acid resin, and optionally control the mechanical strength such as tensile rupture elongation and bending modulus Biodegradable resin composition comprising biodegradable promoter suitable for biodegradable resin and biodegradation promoter is provided.Degradation promoter for biodegradable resin containing cellulose, hemicellulose and lignin, containing 10 to 30% by weight of lignin for 100 mass% of cellulose, hemicellulose and lignin The decomposition promoter for biodegradable resin having a proportion of cellulose content to the content of hemicellulose is 0.5 to 4.0.Biodegradable resin composition comprising 2 to 250 parts by mass of biodegradation promoter and 100 parts by mass of biodegradable resin.No selection
