Claim Text:
1. A telechelic polyamide comprising: a) repeat units derived from polymerizing monomers connected by linkages between the repeat units and functional end groups selected from carboxyl or primary or secondary amine, wherein at least 70 mole percent of telechelic polyamide have exactly two functional end groups of the same functional type selected from the group consisting of amino or carboxylic end groups; b) a polyamide segment comprising at least two amide linkages characterized as being derived from reacting an amine with a carboxyl group, and said polyamide segment comprising repeat units derived from polymerizing two or more of monomers selected from lactams, aminocarboxylic acids, dicarboxylic acids, and diamines; c) wherein at least 10% of the total number of the heteroatom containing linkages connecting hydrocarbon type linkages are characterized as being amide, d) wherein at least 25% of the amide linkages are characterized as being tertiary amide linkages, and e) wherein at least 60 wt. % of said telechelic polyamide segment comprises repeat units of the structure wherein R wherein R
