摘要：PROBLEM TO BE SOLVED: To provide a resin composition which solves problems comprising the remarkable deterioration of thermal stability and hydrolyzing property on melt molding, caused by compounding polybutylene terephthalate (PBT) resin with polylactic acid, holds the mechanical and thermal properties of PBT resin and is afforded with biodegradability. SOLUTION: This polybutylene terephthalate resin composition comprising (A) 100 pts. wt. of PBT resin and (B) 1 to 99 pts. wt. of a biodegradable polylactic acid-based resin is characterized in that the terminal carboxy group concentration of PBT is≤40 eq/ton.
