Patent ID: 6960315

Claim:
A method for producing moldings by an injection molding process which comprises: 1) introducing into an injection mold a molten polyamide formed by reaction of a mixture comprising: a) 80 to 100 mol %, of at least one aliphatic C 4 -C 18 dicarboxylic acid wherein the at least one aliphatic C 4 -C 18 dicarboxylic acid is selected from the group consisting of succinic acid, glutaric acid, adipic acid, pimelic acid, suberic acid, azelaic acid, sebacic acid, undecanedioic acid, dodecanedioic acid, and mixtures thereof; b) 10 to 90 mol % of at least one aliphatic diamine containing from 2 to 20 carbon atoms; c) 10 to 80 mol % of at least one cycloaliphatic diamine; and d) 0 to 80 mol % of at least one polyether diamine, wherein the polyamide contains no dimer fatty acid residues and the sum total of diamines amounts to 100 mol %; and 2) cooling the polyamide.
