Title: Crosslinked Polyamide

Abstract

A crosslinked polyamide material and a process for preparing the crosslinked polyamide material are disclosed. The crosslinked polyamide material comprises a crosslinked chemical combination of (1) a polyamide of the formula: ##STR1## wherein n is between about 50 and 10,000, wherein each R is between 1 and 50 carbon atoms alone and is optionally substituted with heteroatoms, oxygen, nitrogen, sulfur, or phosphorus and combinations thereof, wherein multiple of the R are in vertically aligned spaced relationship along a backbone forming the polyamide, and wherein two or more of the R contain an amino group; and (2) a crosslinking agent containing at least two functional groups capable of reacting with the amino groups of the polyamide. In one embodiment of the invention, the crosslinking agent is an aliphatic or aromatic isocyanate compound having 2 or more --N.dbd.C.dbd.O groups. In another embodiment of the invention, the crosslinking agent is an aliphatic aldehyde or aromatic aldehyde compound having 2 or more --CHO groups. In still another embodiment of the invention, the crosslinking agent is selected from a phosphine having the general formula (A).sub.2 P(B) and mixtures thereof, wherein A is hydroxyalkyl, and B is hydroxyalkyl, alkyl, or aryl. In yet another embodiment ofmore » the invention, the crosslinking agent is selected from the group consisting of epoxy resins having more than one epoxide group per molecule.« less
