    Abstract: Mixtures comprising (A) from 99.5 to 40 parts by weight of polyurethane elastomers comprising (a) polyester-polyols having a functionality of from 2 to 6 and molecular weights of from 600 to 6,000, prepared by polycondensation of approximately equal molar amounts of alkanedicarboxylic acids containing 4 to 12 carbon atoms and alkanediols containing 2 to 10 carbon atoms or hydroxyalkanemonocarboxylic acids containing 5 to 11 carbon atoms, or lactones thereof, and b) hydrocarbon diisocyanates containing 4 to 15 carbon atoms, and (B) from 0.5 to 60 parts by weight of vinyl chloride polymers, which contain, as component (B), vinyl chloride homopolymers having K values of greater than 40, are highly suitable as raw materials for the preparation of adhesive formulations, in particular for bonding structures made from natural and/or synthetic rubber.

    Abstract: Contact adhesive dispersions contain (A) an aqueous dispersion of a copolymer A which has a glass transition temperature below 0 DEG C. and consists of (a) from 50 to 99% by weight of esters of acrylic acid with non-tertiary alkanols, (b) from 0 to 50% by weight of esters of acrylic or methacrylic acid and/or vinyl esters and/or (meth)acrylonitrile and/or styrene and/or tert.-butyl acrylate, (c) from 0.5 to 5% by weight of monoolefinically unsaturated carboxylic acids and/or their amides which are unsubstituted or substituted at the nitrogen atoms by alkyl and/or alkylol radicals, and/or hydroxyalkyl (meth)acrylates, and (d) from 0.5 to 5% by weight of carbonyl-containing monomers and (B) from 0.05 to 2 moles of a water-soluble dihydrazine compound per mole of carbonyl groups present in the copolymer A.
