A process for producing a thermoplastic elastomer, comprising: providing a polyether composition comprising at least a glycol-terminated first polyether having a number average molecular weight of 400 to 6000 and up to 15% by weight of pyrogenic silicon oxide having C1-C8 alkylsilyl groups or acrylate or methacrylate groups on its surface, the polyether composition is combined with optionally a further first polyether and a) at least one dicarboxylic acid and at least one organic diol having a molecular weight of less than 250 or b) at least one dicarboxylic acid ester terminated polyamide to form a prepolymer composition, and the prepolymer composition is allowed to polymerize to form a thermoplastic elastomer. 生产热塑性弹性体的方法，包括：提供至少包含数均分子量为400-6000的经二醇封端的第一聚醚和最高达15重量％的在其表面具有C1-C8烷基甲硅烷基基团或者丙烯酸酯或甲基丙烯酸酯基团的热解法氧化硅的聚醚组合物，将所述聚醚组合物与任选的另外的第一聚醚和a)至少一种二羧酸和分子量小于250的至少一种有机二醇或b)至少一种二羧酸酯封端的聚酰胺组合，以形成预聚物组合物，并允许所述预聚物组合物聚合以形成热塑性弹性体。
