    Abstract: Synthetic resins are obtainable by chemically bonding one or more compounds of the general formula I (* CHEMICAL STRUCTURE *) (I) where R1 is -OH, -NH2, (* CHEMICAL STRUCTURE *) -NHR3 or (* CHEMICAL STRUCTURE *) R2 is -H, -CH3 or -C2H5, R3 is -CmH2m+1, where m is from 1 to 6, R4 is -H or -CH3 and n is from 1 to 12, via the oxygen or nitrogen atom of R1 to one or more polymers A which consist of a) from 50 to 100% by weight of one or more esters of acrylic or methacrylic acid with monohydric alcohols of 1 to 18 carbon atoms or a mixture of these esters (monomers a) and b) from 0 to 50% by weight of other copolymerizable monomers (monomers b) in polymerized form, in amounts such that the synthetic resin contains from 0.01 to 1 mole of double bonds per kg of polymer A. After exposure to ultraviolet light or to electrons, these synthetic resins are suitable as contact adhesives.

    Abstract: Prodn. of glycerol acrylate versatate carboxyalkanoate esters of formula (I) is effected by reacting a glycerol acrylate versatate ester of formula (II) with an equimolar amt. of a satd. or monoolefinically unsatd. cyclic dicarboxylic anhydride (III) having 4-5 atoms and n O atom in the ring, the reaction being effected at 50-150 deg.C in the presence of an esterification catalyst: In (I)-(II) R=versatyl; one of R1 and R2 is H and the other is COCH=CH2; one of R3 and R4 is COR'COOH and the other is COCH=CH2; R'=4-5C linear alkylene opt. substd. by alkyl gps., N.B., the definition of R' is not in accord with the definition of cpd. (III) or with the exemplified cpds. succinic and maleic anhydride.

    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.

    Abstract: Compounds of the general formulae I and II where R is versatyl and R' is unsubstituted or alkyl-substituted straight-chain alkylene of 4 or 5 carbon atoms can be prepared by reacting the versatic ester of 1,3-dihydroxy-propyl-2 acrylate and/or of 2,3-dihydroxy-propyl-1 acrylate with equimolar amounts of saturated or monoolefinically unsaturated cyclic dicarboxylic anhydrides having 4 or 5 carbon atoms and an oxygen atom in the ring at from 50 DEG to 150 DEG C. in the presence of customary esterification catalysts and can be used as reactive diluents in radiation-curable contact adhesives.
