Abstract
Provided is a polymer prepared by using a vegetable oil-derived component and favorably used as a polylactic acid resin-softening agent that is effective in softening the polylactic acid resin while preserving the transparency of the polylactic acid resin and simultaneously resistant to bleeding out (extraction) of itself from the polylactic acid resin. Also provided are a resin mixture of the resin composition and a polylactic acid resin as well as a film or sheet prepared by using the resin mixture. The polymer (C) according to the present invention has an epoxidized vegetable oil segment (A) and a polylactic acid segment (B). The resin mixture according to the present invention is a mixture of the polymer (C) and the polylactic acid resin (D) at a (C)/(D) ratio of 10/90 to 50/50 (weight ratio).
