    Abstract: The process involves the free-radical polymerisation of… (a) from 50 to 100%, based on the weight of all the monomers, of C1- C20-alkyl (meth)acrylates,… (b) from 0 to 20%, based on the weight of all the monomers, of polyolefinically unsaturated monomers and… (c) from 0 to 30%, based on the weight of all the monomers, of further monoolefinically unsaturated monomers,… in aqueous emulsion in the presence of a preformed, water-dispersed solution copolymer (A) made from… (I) from 1.5 to 15% by weight of monomers containing 3 to 10 carbon atoms and one carboxyl or carboxylic anhydride group,… (II) from 30 to 98.5% by weight of C1-C20-alkyl acrylates or methacrylates,… (III) from 0 to 60% by weight of vinylaromatic compounds,… (IV) from 0 to 20% by weight of monoolefinically unsaturated carbonyl compounds and… (V) from 0 to 20% by weight of further monomers other than those mentioned under (I) to (IV),… and a solution copolymer (B) comprising from 40 to 100% by weight of monomers (II) and from 0 to 60% by weight of monomers (III) to (V).

    Abstract: The polymer dispersions are obtainable by dispersing a mixture of… 15 - 70% by weight of a copolymer (A) comprising… (I) 1.5 - 15% by weight of copolymerisable compounds containing 3 to 10 carbon atoms and one carboxyl or carboxylic anhydride group,… (II) 65 - 98.5% by weight of C1- to C20-alkyl acrylates or methacrylates,… (III) 0 - 20% by weight of vinylaromatic compounds,… (IV) 0 - 20% by weight of copolymerisable carbonyl compounds,… (V) 0 - 10% by weight of further copolymerisable organic compounds not mentioned under (I) to (IV),… and 30 - 85% by weight of a copolymer (B) comprising… 60 - 100% by weight of monomers (II) and… 0 - 40% by weight of monomers (III) to (V),… with the proviso that the copolymers (A) and (B) together contain more than 65% by weight of alkyl (meth)acrylates (II) as synthesis component whose homopolymers have glass transition temperatures of below 0 DEG C, and that at least one of the copolymers (A) and (B) contains the monomers (IV) as synthesis component,… in water with addition of ammonia and a polyhydrazide (C). … The dispersions are used as contact adhesives and as adhesives for multilayer films.
