    摘要: A copolyamide resin containing a dimerized fatty acid as a copolymer component, which has (1) at least 25 equivalent %, based on the total number of terminal groups, of hydrocarbon groups having from 6 to 22 carbon atoms at its terminals, (2) a content of a dimerized fatty acid of from 0.1 to 40% by weight based on the total amount of the resin, and (3) a melt viscosity as measured at 240.degree. C. of from 2,000 to 15,000 poise.

    摘要: Disclosed herein is a process for producing a polyamide comprising polymerizing at least one monomer of polyamide in the presence of(1) a hydrocarbon polymer having at least one group selected from the group consisting of a carboxyl group, a derivative group of carboxylic acid, an amino group, and a hydroxyl group, or(2) a polymer produced by reacting the hydrocarbon polymer with a polyamide, or polymerizing at least one monomer of polyamide in the presence of the hydrocarbon polymer.
