PURPOSE:To obtain a resin composition outstanding in strength and adhesive force to surface-treating material, capable of giving molded articles of improved surface appearance, by incorporating a polyamide with inorganic filler and fatty acid ester of polyoxyethylene sorbitan. CONSTITUTION:The objective composition can be obtained by incorporating (A) 100pts.wt. of a polyamide (pref. nylon 6) with (B) 30-100pts.wt of inorganic filler with an average particle size <=20mum and (C) 0.05-0.6pt.wt. of monoester(s) of formula I and/or II (R is 10-20C alkyl or alkenyl, pref. of formula III or IV; n1-n3 are each 1-20) prepared by the following process; an aliphatic ester of polyoxyethylene sorbitan (pref. sorbitol) is heated to effect ring formation to form a sorbitan having furanol ring and/or pyranose ring, which is then esterified with monocarboxylic acid followed by reaction with ethylene oxide. |
