METHOD FOR PRODUCING POLYAMIDE COMPOSITE MATERIALS CONTAINING SILICON

摘要

The invention relates to a method for producing polyamide composite materials containing silicon, comprising the copolymerisation of: a) at least one silicon compound (SV) having at least one silicon atom, said silicon atom having at least one lactamyl group of formula (A) bonded by means of the nitrogen atom thereof; b) the method also comprises copolymerisation with at least one comonomer (CM) that is selected from among ammonium salts of dicarboxylic acids, amino acids, amino acid amides and lactams. In formula (A), m represents a whole number between 1 and 11, in particular in between 2 and 9, and specifically 3, and # represents the connection to the silicon atom of the compound (SV).

主权项

1. A process for producing a silicon-containing polyamide composite material, comprising copolymerizing:
a. at least one silicon compound SV comprising a silicon atom comprising a lactamyl radical attached via its nitrogen atom and having a formula (A), where m is an integer from 1 to 11 and # is the point of attachment to the silicon atom; with b. at least one comonomer CM selected from the group consisting of an ammonium salt of a dicarboxylic acid, an aminocarboxylic acid, an aminocarboxamide, and a lactam, wherein the at least one comonomer CM is such that water is formed during the copolymerizing, or water is added to the copolymerization reaction.
