A telechelic polyamide comprising: a) 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; b) wherein said repeat units derived from polymerizing monomers connected by linkages between the repeat units and functional end groups are selected from carboxyl or primary or secondary amine, wherein at least 70 mole percent of the telechelic polyamide have exactly two functional amino end groups; 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 70 wt.% of said telechelic polyamide comprises repeat units of the structure wherein R a is the alkylene portion of the dicarboxylic acid and is a cyclic, linear, or branched alkylene group of 2 to 36 carbon atoms, optionally including up to 1 heteroatom per 3 or 10 carbon atoms of the diacid; and wherein R b is a linear or branched alkylene group of 2 to 60 carbon atoms, optionally being or including cyclic or heterocyclic portions, optionally including up to 1 heteroatom per 3 or 10 carbon atoms; and R c and R d connect together to form a single linear or branched alkylene group of 1 to 8 carbon atoms. a) 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; b) wherein said repeat units derived from polymerizing monomers connected by linkages between the repeat units and functional end groups are selected from carboxyl or primary or secondary amine, wherein at least 70 mole percent of the telechelic polyamide have exactly two functional amino end groups; 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 70 wt.% of said telechelic polyamide comprises repeat units of the structure wherein R a is the alkylene portion of the dicarboxylic acid and is a cyclic, linear, or branched alkylene group of 2 to 36 carbon atoms, optionally including up to 1 heteroatom per 3 or 10 carbon atoms of the diacid; and wherein R b is a linear or branched alkylene group of 2 to 60 carbon atoms, optionally being or including cyclic or heterocyclic portions, optionally including up to 1 heteroatom per 3 or 10 carbon atoms; and R c and R d connect together to form a single linear or branched alkylene group of 1 to 8 carbon atoms. wherein R a is the alkylene portion of the dicarboxylic acid and is a cyclic, linear, or branched alkylene group of 2 to 36 carbon atoms, optionally including up to 1 heteroatom per 3 or 10 carbon atoms of the diacid; and wherein R b is a linear or branched alkylene group of 2 to 60 carbon atoms, optionally being or including cyclic or heterocyclic portions, optionally including up to 1 heteroatom per 3 or 10 carbon atoms; and R c and R d connect together to form a single linear or branched alkylene group of 1 to 8 carbon atoms.
