    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.

(ISO 307, 0.5% in 96% H2SO4 at 25 deg.C) (VA) 30-100 ml/g, where VA-VB is at least 30; (C) 0-50% fibrous or particulate fillers or their mixts., (D) 0-40% rubber-elastic polymer; (E) 0-30% conventional additives. Pref. VA = 100-200 ml/g. VB = 40-80 ml/g. VA-VB is at least 50. (I) contain 50-99% (A) and 1-5% (B). (A) is PET and/or polybutylene terephthalate (II). (B) is polyhexamethylene adipamide (III) and/or polycaprolactam and/or partly aromatic partly crystalline copolyamide. USE/ADVANTAGE - Prepn. of fibres, films, and moulded articles partic. in the motor vehicle industry. (I) have improved flowability compared with compsns. not contg. (B), independently of amt. and type of (E), reduced cycle time, and improved toughness with greater plastic deformation before final break
