    Abstract: Thermoplastic molding composition contains (A) 20-96 wt.% star polymer, obtained by polymerization of vinyl-aromatic monomers with a branched monomer, which contains NOTLESS 2 vinyl-aromatic functional groups, (B) 3-50 wt.% copolymer of vinyl-aromatic monomer, 1,1-diphenylethylene and optionally diene, (C) 1-15 wt.% polyarylene ether, (D) 0-5 wt.% nucleating agent, (E) 0-5 wt.% antioxidant, (F) 0-5 wt.% stabilizer and (G) 0-50 wt.% fibrous or particulate filler. Independent claims are also included for (a) the production of the composition by mixing the components at 270-320 degrees C; and (b) fibers, films and moldings based on the composition

    Abstract: PCT No. PCT/EP95/04809 Sec. 371 Date Jun. 16, 1997 Sec. 102(e) Date Jun. 16, 1997 PCT Filed Dec. 7, 1995 PCT Pub. No. WO96/18682 PCT Pub. Date Jun. 20, 1996Toughened vinyl aromatic compounds, in particular high impact polystyrene, are prepared by a continuous process in which the vinyl aromatic compound and the impact modifier, an elastomeric block copolymer, are each prepared separately in a reaction zone by anionic polymerization, with or without heat exchange with the environment and, if required, with the addition of a solvent, and are polymerized until complete conversion is achieved, and the living chain ends are terminated in a manner known per se, and a thermoplastic, toughened molding material is based on a vinyl aromatic compound having a residual content of less than 50 ppm of monomers and less than 100 ppm of oligomers.

    IPC: C08L53/02

    Abstract: The invention relates to a mixture, comprising a) 5 to 50 wt. % of a block copolymer (A), with one or more block copolymers (B/S)A, each made from 65 to 95 wt. % vinylaromatic monomers and 35 to 5 wt. % dienes with a glass transition temperature TgA in the range 40~ to 90 ~C, b) 95 to 50 wt. % of a block copolymer B, with at least one hard block (S) made from vinylaromatic monomers and one or more copolymer blocks (B/S)B, each made from 20 to 60 wt. % vinylaromatic monomers and 80 to 40 wt. % dienes and a glass temperature TgB in the range -70~ to 0 ~C, c) 0 to 45 wt. % of a block copolymer (C) different from (A) and (B), or polystyrol and d) 0 to 6 wt. % of a plastifier and the use thereof for the production of shrink films.

    Abstract: A rubber elastic block copolymer has at least one block A made of polymerise d units of a vinyl aromatic monomer that forms a hard phase and/or a block B with diene monomers that forms a first rubber elastic (soft) phase, and at least one elastomer block B/A with polymerised units of both a vinyl aromatic monomer and a diene that for ms if required a second or additional soft phase. The glass transition temperature T g of block A is higher than 25 .degree.C and that o f blocks B or B/A is lower than 25 .degree.C. The phase volume ratio between blocks A and B/A is selected so that the hard phase represents 1 - 40 % by volume of the total block copolymer and the diene amounts to less than 50 % by weight.
