  • Polymer dispersions as an additive in building materials
    Patent number: 6809148
    Abstract: Polymer dispersions comprise at least one copolymer which contains, as polymerized monomers, a) from 25 to 70% by weight of at least one conjugated aliphatic diene, b) from 25 to 70% by weight of at least one vinylaromatic monomer, c) from 2.5 to 15% by weight of at least one monoester of a C2-C10-alkanediol with acrylic acid or methacrylic acid or c′) from 0.1 to 10% by weight of at least one alkylpolyethylene glycol (meth)acrylate of the formula (I) where R1 is hydrogen or methyl, R2 is C1-C4-alkyl and n is an integer from 1 to 100, or c″) from 2 to 15% by weight of a mixture of the monoester c) and the alkylpolyethylene glycol (meth)acrylate c′), d) from 0 to 1.0% by weight of ethylenically unsaturated monomers which have at least one acid group, or salts thereof, e) from 0 to 5.0% by weight of ethylenically unsaturated nitriles and f) from 0 to 1.0% by weight of amides of &agr;,&bgr;-ethylenically unsaturated mono- and dicarboxylic acids.

  • Copolymers and mixtures which are self-curable with atmospheric humidity
    Patent number: 5532329
    Abstract: Copolymers which are self-curable with atmospheric humidity and are based on acrylic, methacrylic and/or vinyl esters which have been prepared using silicon-containing regulators, and mixtures of such polymers with crosslinkers, are suitable as adhesive, sealing and coating compositions which are self-curable with atmospheric humidity.

  • Nonaqueous plastics formulations
    Patent number: 5120795
    Abstract: A) 100 parts by weight of at least one finely divided plastic which consists ofa) from 30 to 100% by weight of methyl methacrylate (monomer I),b) from 0 to 70% by weight of an acrylate of a C.sub.1 -C.sub.8 alkanol or of a methacrylate of a C.sub.2 -C.sub.8 -alkanol or of a mixture of these monomers (monomers II),c) from 0 to 15% by weight of an .alpha.,.beta.-monoethylenically unsaturated mono- and/or dicarboxylic acid of 3 to 5 carbon atoms (monomers III),d) from 0 to 20% by weight of copolymerizable monomers which contain at least one nitrogen base group and/or one hyroxyl group (monomers IV) ande) from 0 to 5% by weight of other copolymerizable monomers (monomers V), in polymerized form,B) from 30 to 300 parts by weight of at least one polymer which consists ofa) from 5 to 100% by weight of glycidyl acrylate and/or methacrylate (monomers VI),b) from 0 to 95% by weight of an acrylate or methacrylate of a C.sub.1 -C.sub.
