Title:
水溶性または水膨潤性のスルホ基含有コポリマー、その製造方法およびその使用
Document Type and Number:
Japanese Patent JP4187859
Kind Code:
B2
Abstract:
Water-soluble or -expandable, sulfo group-containing copolymers with monomer units derived from (meth)acrylamido-alkanesulfonic acid, optionally substituted (meth)acrylamide and/or N-vinylamide, (meth)acryloyloxy-alkyl- or (meth)acrylamidoalkyl-trialkyl-ammonium halide and other (meth)acrylate ester or vinyl monomers. Water-soluble or -expandable, sulfo group-containing copolymers comprise (a) 3-96 mol% units of formula (I), (b) 3-96 mol% units (IIa) and/or (IIb), (c) 0.05-75 mol% units (III) and (d) 0.01-50 mol% units (IV); R<1> = H or methyl; R<2>-R<4> = H, 1-6C aliphatic hydrocarbyl or 6-14C aryl (optionally substituted with 1-6C alkyl groups); M = H, mono- or divalent metal cation, ammonium and/or organic amine residue; a = 0.5 or 1; R<5>, R<6> = H, optionally substituted 1-20C aliphatic hydrocarbyl, 5-8C cycloaliphatic hydrocarbyl or 6-14C aryl, or (if Q is not H in IIb) R<5> + R<6> may be -CH2-(CH2)y-; y = 1-4; Q = H or -CHR<5>R<7>; R<7> = H, 1-4C aliphatic hydrocarbyl, -COOH or -COOMa; Y = O, NH or NR<5>; R<8> = R<5> or R<6>; X = anion, especially halide, 1-4C alkylsulfate or 1-4C alkylsulfonate; x = 1-6; Z = -COO(CmH2mO)n-R<5> or -(CH2)p-O(CmH2mO)n-R<5>; m = 2-4; n = 0-200; p = 0-20. An Independent claim is also included for a process for the production of these copolymers from the corresponding monomers by aqueous solvent- or gel-polymerisation or inverse suspension polymerisation in organic solvent at -20 to 250 degrees C.
