    • The present invention relates to a thermoplastic resin composition characterized by comprising (A) a thermoplastic resin, (B) an inorganic filler and/or organic filler, and (C) a polyhydroxy alcohol ester of condensed hydroxyfatty acid and/or (C') a condensed hydroxyfatty acid having a degree of condensation exceeding 3. Also, it relates to a method for producing the thermoplastic resin, comprising the steps of blending (C) a polyhydroxy alcohol ester of condensed hydroxyfatty acid and/or (C') a condensed hydroxyfatty acid having a degree of condensation exceeding 3 with (A) a thermoplastic resin previously blended with (B) an inorganic filler and/or organic filler, and melt-kneading the resulting mixture; and to a method for producing the thermoplastic resin composition, comprising the steps of blending (C) a polyhydroxy alcohol ester of condensed hydroxyfatty acid and/or (C') a condensed hydroxyfatty acid having a degree of condensation exceeding 3 at a high concentration with (A) a thermoplastic resin previously blended with (B) an inorganic filler and/or organic filler and blending and/or compounding the above mixture while diluting with (A) a thermoplastic resin or (A) a thermoplastic resin blended with an inorganic filler and/or organic filler.
    • 本发明涉及一种热塑性树脂组合物,其特征在于含有(A)热塑性树脂,(B)无机填料和/或有机填料,和(C)缩合羟基脂肪酸的多羟基醇酯和/或(C') (C)稠合羟基脂肪酸的多羟基醇酯和/或(C')缩合物的步骤,所述(C)稠合羟基脂肪酸具有超过3的缩合度。另外,本发明还涉及生产所述热塑性树脂的方法, (A)预先与(B)无机填料和/或有机填料混合的热塑性树脂,并将所得混合物熔融捏合的缩合度超过3的羟基脂肪酸; (C)浓缩羟基脂肪酸的多羟基醇酯和/或(C')高浓度浓缩度超过3的缩合羟基脂肪酸的步骤,以及 (A)预先与(B)无机填料和/或有机填料共混并且在用(A)热塑性树脂或(A)与无机填料共混的热塑性树脂稀释的同时混合和/或混合上述混合物的热塑性树脂 和/或有机填料。
