Abstract: An expandable rubber modified styrene polymer (I) comprises (A) a continuous phase of polystyrene or a styrene comonomer containing up to 50 wt.% comonomer (B) 5-30 wt.% (w.r.t. polymer mixture) of dispersed rubber particles and (C) 2-15 pts.wt. (w.r.t. 100 pts wt. polymer mixture) of a low binding blowing agent. The rubber particles consists of a butadiene/styrene block copolymer having a compact lamella structure without polystyrene inclusions. Also claimed are: (i) a process for the production of (I) by dissolving (B) in (A) followed by polymerisation of the monomers and processing to a granular form whereby (C) is added during or after polymerisation. (ii) pre-foamed beads having pore walls made of (I).

Abstract: A new catalyst (I) contains 0.01-30 wt% ruthenium or palladium as active metal, optionally together with Group I, VII or VIII transition metal(s), on a carrier (II) in which (novel feature) 10-50% of the pore volume consists of macropores with a pore diameter (PD) of 50-10,000 nm and 50-90% consists of mesopores with a PD of 2-50 nm. Also claimed are (i) a process for conversion of polymers containing multiple C-C bond(s) in presence of (I) and (ii) a process for conversion of organic compounds in the presence of (I) in which the active metal is ruthenium.

Abstract: A process for the preparation of a thermoplastic moulding composition comprising 80 - 50% by weight of a hard matrix of an anionic polymerised vinylaromatic compound and 20 - 50% by weight of a soft phase uniformly distributed in the hard matrix, in each case based on the sum of the hard matrix and the soft phase, characterised in that, in a first step, an elastomeric block copolymer based on a vinylaromatic compound and an alkadiene is polymerised anionically in a weight ratio of 5:95 to 55:45, the living ends of the chain are optionally blocked, and, with a re-addition of an anionic initiator and with stirring, the vinylaromatic compound is polymerised in the presence of the block copolymer and the living ends of the chain are finally blocked again.
