摘要：
A polylactic acid-containing resin composition that include (a) a polylactic acid and (b) a (meth)acrylic copolymer having a molecular weight in excess of 30,000 and that is the reaction product of a monomer mixture including a methyl (meth)acrylate (i) and a (meth)acrylic acid ester (ii) that is different than the methyl (meth)acrylate (i). The (meth)acrylic acid ester (ii) is represented by any one of formula (I): CH2=C(R1)-COO-R2 formula (II): CH2=C(R1)-COO-(CH2CH2O)m-R3, or formula (III): CH2=C(R1)-COO-(CH2CH2O)n-Ph. A method for preparing the (meth)acrylic copolymer is also provided as well as articles formed from polylactic acid-containing resin compositions.
