An aqueous dispersion containing a copolymer comprising

Dispersion contact adhesive having little odor

Aqueous synthetic resin dispersions

Materials which are cross-linkable by ultraviolet radiation under atmospheric oxygen and are based on (meth)acrylate copolymers having a K value of from 10 to 100 are obtained by free radical polymerization, in the presence or absence of a solvent, of

UV-crosslinkable materials based on isoamyl (meth)acrylate copolymers

Dispersions of non-tertiary butyl (meth)acrylate copolymers having glass

Aqueous polymer dispersions which have a long shelf life are obtainable by dispersing a mixture of from 15 to 70% by weight of a copolymer (A) of

Aqueous polymer dispersions having a long shelf life

Aqueous (meth)acrylate copolymer dispersions can be prepared by polymerization of the monomers in two stages having different monomer compositions and with the concomitant use of crosslinking monomers in aqueous emulsion at the usual temperatures in the presence of the conventional emulsifiers and polymerization initiators, from 40 to 99.5% by weight of the total monomers being polymerized in the first stage and from 60 to 0.5% by weight of the total monomers being polymerized in the second stage, by a process in which from 0.5 to 10% by weight, based on the total monomers, of (meth)-acrylamidoglycollic acid and /or its methyl ester and/or its methyl ether are polymerized in the second stage and from 0 to 1.8% by weight, based on the total monomers, of the amidoglycollic acid compounds are polymerized in the first stage, and the resulting copolymer dispersions are used as binders for sheet-like textile fibrous structures.

Preparation of aqueous (meth)acrylate copolymer dispersions in two

Aqueous dispersions of copolymers having a glass transition temperature of not more than -45.degree. C. and a K value greater than 80 consist of not less than 80% by weight of acrylates of alkanols of 8 to 12 carbon atoms, from 1 to 4% by weight of .alpha.,.beta.- monoolefinically unsaturated carboxylic acids and/or their amide derivatives and from 0.1 to 3% by weight of .alpha.-methylstyrene, and are used for the production of self-adhesive structures having good tack at as low as -40.degree. C.
