    摘要: Biodegradable thermoplastic polymer blend compositions are presented in which a first polymer and a second polymer are intimately associated together in a uniform, substantially homogeneous blend. The second polymer of the composition acts to facilitate biodegradation of the composition, and of shaped articles manufactured therefrom, at a rate which is enhanced over that of the most slowly biodegrading individual polymer component of the composition. The composition may further comprise a polysaccharide component, such as a starch component like destructurized starch.
