    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/EP96/05522 Sec. 371 Date Jun. 2, 1998 Sec. 102(e) Date Jun. 2, 1998 PCT Filed Dec. 11, 1996 PCT Pub. No. WO97/21744 PCT Pub. Date Jun. 19, 1997The disclosure relates to a copolymer obtainable by radically initiated polymerization of the following: A) 70-99.9 wt. % an olefinically unsaturated C3-C5 monocarboxylic acid, an olefinically unsaturated C4-C8 dicarboxylic acid or its anhydride, or a mixture of such carboxylic acids; with B) 0.1-30 wt. % one or more multiply olefinically unsaturated carboxylic acid derivatives of formula (I)Z-Y-(CHR3-CH2-X)n-R4(I)in which Z is a vinyl or allyl group or structure (a), R1, R2 are hydrogen or methyl, R3 is hydrogen, methyl or ethyl, R4 is a singly or multiply olefinically unsaturated alkenyl or cycloalkenyl group or a singly or doubly olefinically unsaturated arylalkylene group, X is oxygen or NH, Y is oxygen, NH or N-alkyl, n is a number between 0 and 50; and C) 0-29.9 wt. % other copolymerizable monomers. The proposed copolymer can be used as a thickener or dispergent for aqueous systems.
