摘要

solution, use of a solution, terpolymer, process for preparing terpolymers and use of thermopolymers. the invention relates to a terpolymer solution composed of monomers of components a, b and c, the total amount of which is 100% by weight, a) 5 to 60% by weight of lactams as component a, b) 5 to 60% by weight of equimolar amounts of adipic acid and one or more aliphatic diamines as components b, c) 10 to 70% by weight of equimolar amounts of adipic acid and 4.4 '- diaminodicyclohexialmenthane (dicycan) as components c, in a system of solvent free of aromatic hydrocarbons, containing 50 to 100% by weight of c1-4 alkanol, 0 to 50% by weight of water and a maximum of 10% by weight of other solvents free of aromatic hydrocarbons, in which the total amount of solvent system is 100% by weight and a terpolymer composed of the monomers of components a, b and c, the total amount of which is 100% by weight, a) 15 to 40% by weight of lactams as components a, b) 20 to 45 % by weight of equimolar amounts of adipic acid and one or more aliphatic diamines as a component es b, c) 25 to 60% by weight of equimolar amounts of adipic acid and 4, 4 '- diaminodicyclohexylmethane (dicycan) as component c, except terpolymers composed of 30 to 40% by weight of component a, 30 and 40% in component weight b and 30 to 40% component weight c.
