Abstract:
1. A crosslinkable branched polyamide comprising unsaturated ends wherein the polyamide results from the condensation of 11-aminoundecanoic acid, caprolactam, lauryllactam, diethylenetriamine, undecylenic acid and hexamethylenediamine, the proportion of diethylenetriamine being from 0.05 to 2% by weight with respect to the combination of 11-aminoundecanoic acid, caprolactam, lauryllactam, diethylenetriamine, undecylenic acid and hexamethylenediamine, and wherein said hexamethylenediamine is present in excess so all undecylenic acid is attached to the polymer, wherein said polyamide has more than 2 unsaturated ends, and wherein said polyamide is both branched and crosslinkable and is suitable for use as a thermofusible adhesive.
