Abstract: The production of branched polyamides (I) comprises: (i) mixing (A) 10-99.7 wt% molten polyamide prepolymer with a viscosity number (VN) of 40-90 ml/g with (B) 0.3-6 wt% poly- carboxylic acid with 3-10 free COOH groups and (C) 0-80 wt% other additives and processing aids; followed by (ii) solid-phase post- condensation. Also claimed are thermoplastic moulding materials obtained by this process. Preferably after solid-phase post-condensation, the polyamide has a VN of at least 100 ml/g. Component (B) contains 3 or 4 free COOH groups; preferred (B) is benzene-1,3,5- tricarboxylic or -1,2,4,5-tetracarboxylic acid, biphenyl- -3,5,3',5'-tetracarboxylic acid and/or naphthalene-1,3,5,7- tetracarboxylic acid. The amount of (B) used is 0.4-5.8 wt%. Component (A) consists of polyamide (PA) 66, PA 6/6T and/or PA 66/6T.

Abstract: Highly dilatant copolymer dispersions which contain, as essential components, an emulsion copolymer prepared from 1 to 10% by weight, based on the total amount of monomers employed, of alpha , beta - monoolefinically unsaturated carboxylic acids and other olefinically unsaturated monomers are characterised in that the emulsion copolymer is prepared in the presence of from 5 to 30% by weight, based on the total amount of monomers employed, of an allyl or alkylallyl carboxylate containing 2 or more copolymerisable, olefinic double bonds, or a mixture thereof, where the alkyl radical contains 1 to 4 carbon atoms.
