Abstract
Procedure for obtaining linear, thermoplastic polyaddition products soluble in organic solvents, characterized in that it comprises reacting diisocyanates, compounds that carry two hydroxyl groups in the final position, with a molecular weight of between 400 and 8000 and water and/or diols with a molecular weight less than 400 and/or diamines with a molecular weight less than 400 and/or hydrazines with a molecular weight less than 400 as chain extension agents, which are reacted in combination with a lactam of the general formula ** (See formula) ** where X means a CH group, where R denotes hydrogen and m an integer from 0 to 9 or X means a nitrogen atom, where R means an aliphatic residue, an araliphatic residue or a pyridine residue, optionally substituted by residues lower alkyl and m represents the number 3 > the chain extension agents and lactam being used in amounts corresponding to a molar ratio of 0.1: 1 to 10: 1.
