摘要 |
The invention provides a thermal resistant resin composition comprising 100 parts by weight of polyester (A) having 25-75% by weight of a lactic acid component consisting of 25-75% by weight of a lactic acid-based polymer (a1) and 25-75% by weight of other aliphatic polyester (a2) having a melting point of 100-250 DEG C, and 0.1-70 parts by weight of a crystalline inorganic filler (B) containing 10% by weight or more of SiO2. The thermal resistant resin composition of the invention performs following function: 1) injection molding can be carried out at a mold temperature of Tg or less or around room temperature with a short molding-cycle, 2) quick crystallization velocity and satisfactory crystallinity can be attained in the molding step, and 3) the molded articles have, as a result, excellent thermal resistance and generate properties of low deterioration of a high polymer component and slow embrittlement in use. |
