BIODEGRADABLE NANOCOMPOSITE COMPOSITION COMPRISING A BLEND OF POLYACTIC ACID AND POLYBUTYLENE SUCCINATE WITH EXCELLENT BIODEGRADABILITY

摘要

PURPOSE: A method for manufacturing a biodegradable nanocomposite composition is provided to improve availability of a blend of polybutylene succinate and polyactic acid by adding layered silicate surface-treated with organic materials.;CONSTITUTION: A method for manufacturing a biodegradable nanocomposite composition comprises the steps of: preparing polylactic acid 20~80 weight% and polybutylene succinate 80~20 weight%; adding layered silicate 0.1~10 parts by weight organic surface-treated on the mixed resin; and melt-blending the mixture at 140-200 C for 5-20 minutes.;COPYRIGHT KIPO 2011
