Abstract
Polyamide, whose main chain contains a chemically bound amine selected from the group consisting of 2-methyl-1,5-diaminopentane and 1-amino-2-R-cyclopent-1-ene, where R is a functional group capable of combining with an amino group to form an amide group, and processes for preparing such a polyamide and fibers, films and moldings comprising such a polyamide.

A polyamide whose main chain comprises chemically bound 1-amino-2-R-cyclopent-1-ene wherein R is a functional group capable of combining with an amino group to form an amide group.
A process for preparing a polyamide, which comprises converting monomers suitable for forming a polyamide in the presence of 1-amino-2-R-cyclopent-1-ene, where R is a functional group selected from the group consisting of carboxylic acid, carboxylic ester, carboxylic amide and nitrile, and the main chain of said polyamide comprises chemically bound 1-amino-2-R-cyclopent-1-ene wherein R is present at a level in the range from 0.001 mol % to 2 mol %, based on 1 mol of acid amide groups of said polyamide.
A process for preparing a polyamide, which comprises converting oligomers suitable for forming a polyamide in the presence of 1-amino-2-R-cyclopent-1-ene, where R is a functional group is selected from the group consisting of carboxylic acid, carboxylic ester, carboxylic amide and nitrile and the main chain of said polyamide comprises chemically bound 1-amino-2-R-cyclopent-1-ene wherein R is present at a level in the range from 0.001 mol % to 2 mol %, based on 1 mol of acid amide groups of said polyamide.
A polyamide whose main chain comprises chemically bound 1-amino-2-R-cyclopent-1-ene wherein R is selected from the group consisting of carboxylic acid, carboxylic ester, carboxylic amide and nitrile, and R is present at a level in the range from 0.001 mol % to 2 mol %, based on 1 mol of acid amide groups of said polyamide.
