    Abstract: Thermoplastics moulding compsn. contains (w.r.t. A+B) (A) 5-95 (wt.)% resin(s) consisting of (a1) 8-12C vinylaromatic monomer(s), (a2) alpha,beta-unsatd. dicarbonyl monomer(s) and (a3) elastomer(s) (rubber) and (B) 95-5% polyamide(s). The novelty is that resin (A) is obtd. by grafting (a1) to an unmodified resin in the presence of a3, then modification in the melt at 120-280 deg.C in the presence of a2, using the monomers in such amts. that A consists of 97-50% a1, 0.05-10% a2 and 3-50% a3.

    Abstract: Procedure for applying layers of electrically conductive polymers onto various materials is claimed. Monomers belonging to the gp. of heterocyclic cpds. with 5 or 6 members, which contain nitrogen or sulphur as hetero-atom, are applied onto a material and polymerised by means of an oxidising agent. Soln. of monomer and soln. of oxidising agent are mixed and applied immediately. Or the oxidising agent is applied first followed by the applicn. of the monomer from the gaseous phase. Thiophene, pyrrole and aniline are pref. as monomers.

    Abstract: The invention relates to a transparent, thermoplastic moulding composition containing, based on A + B, A from 5 to 95% by weight of polystyrene which has been produced in a manner known per se by free-radical polymerisation, B from 95 to 5% by weight of a non-elastomeric block copolymer which is branched in a star-shaped manner, built up from, based on B, b1 from 60 to 95% by weight of styrene and b2 from 5 to 40% by weight of at least one conjugated diene having 4 or 5 carbon atoms, which has been prepared by sequential anionic polymerisation using at least one organolithium compound as initiator and in the presence of a solvent, where firstly, in a first process step, an amount of styrene S1 of from 50 to 80% by weight of the styrene, based on the total amount of styrene, is polymerised in the presence of an amount of initiator I1 and then, in a second process step, a smaller amount of styrene S2 is polymerised with simultaneous addition of a further amount of initiator I2, and, in a third process step of the polymerisation, a mixture of a residual amount of styrene, S3, and the total amount of the diene are reacted, followed by coupling and work-up of the reaction product, characterised in that the amount of initiator I1 in the 1st process step is from 0.05 to 1.0 mmol/100 g of total monomer and that, in the 2nd process step, an amount of styrene S2 of from 12 to 47% by weight of styrene, based on the total amount of styrene, ... in the presence of from 0.5 to 10 mmol/100 g ...
