    摘要: Transparent molding compositions are prepared by blending from 50 to 99 parts by weight of a transparent polyamide, and from 1 to 50 parts by weight of a graft copolymer, such that the sum of the parts by weight of the transparent polyamide and the graft copolymer is 100. The graft copolymer is prepared by reacting from 0.5 to 25% by weight, based on the graft copolymer, of a branched polyamine having at least 4 nitrogen atoms and having a number average molecular weight Mn of at least 146 g/mol, with polyamide-forming monomers selected from the group consisting of lactams, w-aminocarboxylic acids, equimolar combinations of diamine and dicarboxylic acid, and combinations thereof.

    摘要: A stable and high-solids aqueous dispersion of blocked isocyanates, containing auxiliary solvent, is prepared by (1) preparing a solution of a polyisocyanate mixture of from 20-70% by weight of a blocked, hydrophilically modified polyisocyanate (A) and from 30-80% by weight of a blocked, hydrophobic polyisocyanate (B) in an auxiliary solvent (G) and (2) adding water to this solution, with intensive mixing, in an amount which is such as to give a two-phase system comprising a disperse polyisocyanate phase and a continuous, aqueous phase containing auxiliary solvent. In a preferred embodiment of the invention dispersions are prepared which are virtually free from auxiliary solvent, by first adding a portion of water to the solution (1), substantially removing the auxiliary solvent with intensive mixing and then adding a second portion of water with intensive mixing to the mixture comprising the polyisocyanates (A) and (B) and the first portion of water.
