Abstract: Foam sheets of high compressive strength are produced by extrusion of a mixture of a styrene polymer and 5 to 16% by weight of a blowing agent mixture which contains a) from 3 to 70% by weight of an alcohol or ketone having a boiling point of between 56 and 100 DEG C b) from 0 to 50% by weight of carbon dioxide, c) from 0 to 88% by weight of a saturated C3- to C5-hydrocarbon, and d) from 2 to 90% by weight of at least one fluorinated hydrocarbon which boils at between -30 DEG and +30 DEG C. p

Abstract: The thermoplastic moulding compositions contain - based on the sum of A and B - A: from 75 to 97% by weight of a polystyrene A as the hard matrix, B: from 3 to 25% by weight of a particulate, rubber-elastic (co)polymer B essentially based on butadiene or copolymers thereof, itself comprising - based on B - B1: from 40 to 98% by weight of a (co)polymer B1 having a mean particle size of from 100 to 600 nm, B2: from 2 to 60% by weight of a particle mixture B2 which is itself built up from - based on B2 - B21: from 1 to 60% by weight of a (co)polymer B21 having a mean particle size of from 200 to 1200 nm, and B22: from 40 to 99% by weight of a (co)polymer B22 having a mean particle size of from 1200 to 8000 nm, where the (co)polymer B1 has a capsule particle morphology and the (co)polymers B21 and B22 have a cell and/or entangled particle morphology.

Abstract: Gels (I) for thermotropic layers, obtained by irradiation of a mixture (I') with high-energy light. Mixture (I') contains (a) a polymer derived from (A) 60-99.9 wt% unsaturated lactams or vinyl ethers, (B) 0-20 wt% unsaturated crosslinkers, (C) 0.1-30 wt% monomers with acid or acid anhydride group(s) and (D) 0-20 wt% other comonomers, (b) radically polymerisable monomers and (c) water and/or organic solvent. Also claimed is (i) a process for the production of gels with thermotropic properties (I) by irradiating mixture (I'), (ii) glazing systems with thermotropic properties obtained from (I), and (iii) components for thermal insulation obtained from (I).

Abstract: Thermoplastic moulding materials based on polystyrene (PS) are claimed (I); (I) contain 50-99 wt.% PS or impact PS (A; obtd. by radical polymerisation of styrene, opt. in the presence of a rubber) and 1-50 wt.% PS with mol.wt. distribution (Mw/Mn)= 1.2 or below (B; obtd. by anionic polymerisation); (B) has Mn= 30,000-80,000, and (A) has Mn above that of (B). Pref. (I) contain 60-99 wt.% (A) and 1-40 wt.% (B). - Pref. (A) is produced by bulk or soln. polymerisation, as described, e.g. is US-PS 2694692, and (B) is produced by anionic polymerisation with a Li initiator; (A) and (B) are blended in the melt, pref. in an extruder.
