Modified polyamide composition comprising at least one phenolic compound

摘要

A phenolic compound for manufacturing a modified polyamide that has an increased degree of crystallinity is described. A polyamide composition comprising at least one such phenolic compound and optionally reinforcing fillers or extenders is also described. The composition is preferably a composition to be molded, for example in the form of granules or powder, that is used for the manufacture of articles by an injection-molding process.

主权项

1. A method of manufacturing a polyamide composition comprising at least one polyamide and a compound of formula (I): in which R1 is a hydrogen atom, a methoxy, an NH2, a methyl, N2H3, or a benzene, R2 is a hydrogen atom, and R3 is methoxy or an ethoxy, wherein the polyamide is selected from the group consisting of PA 66, PA 610, PA 612, PA 6.66, PA 46, MXD6, PA 66/6T, PA 6, PA 11, and PA 12, and wherein said composition comprises from 1% to 15% by weight of compound of formula (I), relative to the total weight of the composition; said method comprising adding said compound of formula (I) during polymerization of said polyamide in the molten state, in the presence of the monomers of the polyamide.
