Title:
POLYAMIDE COMPOSITION AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/120863
Kind Code:
A1
Abstract:
Provided is a polyamide composition, which may effectively improve the formation of a carbide at a die orifice during injection molding or granulation. The present invention improves the formation of a carbide at a die orifice during injection molding by means of the synergistic effect of a benzofuranone compound and a soap salt of K/Na/Ca/Mg/Ba/Zn/Li/Al metals. Specifically, a benzofuranone compound has the function of capturing a C free radical in polyamide, and the soap salt of the K/Na/Ca/Mg/Ba/Zn/Li/Al metals may have a nucleation effect, together preventing the local temperature during injection molding from being too high thereby leading to the formation of a carbide, and especially preventing the adhesion thereof to a die orifice.
