Abstract: A graft copolymer prepared using the following monomers:a) from 0.5 to 25% by weight, based on the graft copolymer, of a polyamine having at least 11 nitrogen atoms and a number-average molar mass Mn of at least 500 g/mol;b) polyamide-forming monomers selected from the group consisting of lactams and .omega.-amino-carboxylic acids;c) oligocarboxylic acid selected from the group consisting of from 0.015 to about 3 mold of dicarboxylic acid and from 0.01 to about 1.2 mol% of tricarboxylic acid, in each case based on lactam and/or .omega.-aminocarboxylic acid, where the amino group concentration in the graft copolymer is from 100 to 2500 mmol/kg, has improved resistance to solvents and fuels.

Abstract: Degradation acids obtained in the synthesis of carboxylic acids, in particular dicarboxylic acids, having from 8 to 16 carbon atoms may be isolated by separating the degradation acids in the form of a solid from the crude reaction mixture, then washing the degradation acids in the form of an oil with water at an elevated temperature. The resulting degradation acids having low oxidant and metal contents, and the metal catalyst may be recirculated back to the process.
