摘要

Use of a succinic acid ester compound (I) as a molecular weight reducing additives for the preparation of polyamide molded mass. Use of a succinic acid ester compound (I) of formula (R-(O-C(=O)-Y 1>-C(=O)-OH) n), as a molecular weight reducing additives for the preparation of polyamide molded mass. R, Y 1>1-30C aliphatic or aromatic carbon further optionally with an heteroatom such as N, O, S or P; and n : 1-20. Independent claims are included for: (1) a polyamide molded material comprising at least a polyamide with a relative solution viscosity of 2.6-3.2 in m-cresol, and (I); and (2) a method for the preparation of the polyamide molded mass comprising melt mixing the polyamide and (I) in a multi-shaft extruder.
