ADDITIVE FOR POLYAMIDE MOULDING COMPOUNDS AND USE THEREOF

摘要

The invention relates to an additive having at least two functionalities being able to undergo a condensation reaction in combination with a tetraalkylpiperidinyl radical and also a tertiary amine functionality. By the combination of these functionalities, a universal additive can be provided, which, on the one hand, makes possible a narrower molar mass distribution and, at the same time, improves the performance for spun polymers. According to the invention, likewise corresponding additivated polyamide moulding compounds and also an additive solution are provided. The additives according to the invention are used in particular in the production of polyamide for textile applications.
