LACTIC ACID POLYMER COMPOSITION, MOLDED ARTICLE MADE OF SAME, AND METHOD FOR PRODUCING SUCH MOLDED ARTICLE

摘要

Disclosed is a lactic acid polymer composition excellent in transparency, heat resistance and productivity. Also disclosed are a molded article made of such a composition, a sheet, a multilayer sheet, a thermoformed article obtained by secondary forming the sheet or the multilayer sheet, and a productive method for producing such a thermoformed article. Specifically disclosed is a lactic acid polymer composition containing 100 parts by weight of a lactic acid polymer (A), 0.1-3 parts by weight of an organic crystal nucleator (B) containing an aliphatic carboxylic amide having an amide bond, and 0.1-7 parts by weight of a crystallization accelerator (C). A thermoformed article can be obtained with excellent productivity by thermoforming a sheet composed of such a composition at 60-130°C.
