    Abstract: A process for the continuous anionic polymerization or copolymerization of styrene or diene monomers using an alkali metal alkyl compound as polymerization initiator is carried out in the presence of an alkyl- or arylmetal compound of an element which occurs in at least divalent form as rate regulator, preferably under non-isothermal conditions and without back-mixing in a tubular or tube-bundle reactor, preferably using an alkyl- or arylmetal compound A of the formula R1M1 and an alkyl- or arylmetal compound B of the formula R2nM2 in a molar ratio between B and A of from 0.1:1 to 500:1, whereM1 is Li, Na or K;R1 is hydrogen, C1-C20-alkyl, C6-C20-aryl, or C7-C20-alkyl-substituted aryl;M2 is an n-valent element from group 2a, 2b or 3a of the Periodic Table; andR2 is hydrogen, halogen, C1-C20-alkyl or C6-C20-aryl; and a special anionic polymerization initiator containing no Lewis base.

    Abstract: PCT No. PCT/EP95/02207 Sec. 371 Date Dec. 17, 1996 Sec. 102(e) Date Dec. 17, 1996 PCT Filed Jun. 8, 1995 PCT Pub. No. WO95/35335 PCT Pub. Date Dec. 28, 1995An elastomeric block copolymer comprising at least one block A having polymerized units of a vinylaromatic monomer and forming a rigid phase and at least one elastomeric block B/A having polymerized units of both vinylaromatic monomers and of a diene and forming a flexible phase, and glass transition temperature Tg of the block A being above 25 DEG C. and that of the block B/A being below 25 DEG C. and the phase volume ratio of block A to block B/A being chosen so that the amount of the rigid phase in the total block copolymer is 1 to 40% by volume and the amount of the diene is less than 50% by weight.

    Abstract: PCT No. PCT/EP97/04912 Sec. 371 Date Mar. 17, 1999 Sec. 102(e) Date Mar. 17, 1999 PCT Filed Sep. 9, 1997 PCT Pub. No. WO98/12256 PCT Pub. Date Mar. 26, 1998The invention relates to thermoplastic molding compositions comprising A) from 30 to 98% by weight of a graft copolymer comprising aK) from 30 to 90% by weight of an elastomeric graft core, aS) from 10 to 70% by weight of a graft shell comprising aS/1) from 50 to 100% by weight of a styrene compound or a C1-C8-alkyl acrylate or methacrylate, or a mixture thereof, and aS/2) from 0 to 50% by weight of one or more other monomers, B) from 1 to 50% by weight of a thermoplastic polymer and C) from 1 to 70% by weight of an elastomeric block copolymer prepared by anionic polymerization of the monomers with addition of a potassium compound soluble in non-polar solvents (Step 1) followed by hydrogenation of all or virtually all the olefinic double bonds of the polymer obtained in Step 1, as described in greater detail herein.
