    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: The invention pertains to a process for producing impact-resistant modified polystyrene molding compounds by continuous anionic polymerization of styrene monomers in the presence of a rubber in a single reaction zone, wherein a styrene solution containing as rubber a styrene-butadiene block rubber or a mixture of a styrene-butadiene block rubber with a polybutadiene rubber, the styrene content of which, relative to the rubber or rubber mixture, is between 10 and 90 wt %, is fed to a reaction mixture, the polymer content of which is above the phase inversion point. The invention also pertains to a molding compound produced by this process and its use in manufacturing sheets and moldings.
