PURPOSE:To obtain a composition giving good releasability and surface characteristics even with low-temperature mold, free from bleedout when used, by incorporating a polyester consisting mainly of PET with a polymer with its side chain constituted by polyether residue and/or aliphatic polyester residue. CONSTITUTION:The objective composition can be obtained by incorporating (A) 100pts. by wt. of a polyester with ethylene terephthalate accounting for >=80mol% of the total recurring unit with (B) 0.5-80pts. by wt. of a polymer with its side chain constituted by polyether residue and/or aliphatic polyester residue of a molecular weight 90-5,000. In addition, 10-150pts. by wt. of fibrous reinforcer and/or powdery inorganic filler may be incorporated. The component (B) should be derived from polyalkylene glycol monomethacrylate and/or polylactone monomethacrylate. |
