PROBLEM TO BE SOLVED: To provide a method for producing a polylactic acid copolymer resin having improved heat-resistance and applicable in a wide application range by a simple production method. SOLUTION: The method for producing a polylactic acid copolymer resin containing (A) a bisphenol compound component and (B) a polylactic acid component comprises the copolymerization of (A) 1-50 mass% bisphenol compound having a number-average molecular weight of≤10,000 and (B') 99-50 mass% raw material compound for the polylactic acid. More particularly, the raw material compound B' for the polylactic acid is a lactide. COPYRIGHT: (C)2008,JPO&INPIT
