Abstract: Readily filterable and deodorizable aqueous dispersions of pressure-sensitive adhesive, especially for self-adhesive labels, having solids contents of more than 65%, can be prepared with readily reproducible properties by copolymerizing esters of acrylic and/or methacrylic acid in the presence of less than 50 ppm of inhibitor and, preferably, in the presence of from 0.01 to 5% by weight of reducing agent by a special emulsion technique. The highly concentrated pressure-sensitive adhesive dispersion, subsequently deodorized with steam, is free from coagulum and seediness.

Abstract: A process for the production of low-viscosity, aqueous polymer dispersions (APD), with polymer concentrations of at least 50 vol% and viscosities of less than 1000 mPa.s, comprises radical emulsion polymerisation of ethylenic monomers (except vinyl and vinylidene halides), by the monomer addition method, in the presence of an initiator and small amounts of water-miscible organic solvent(s) (I). Also claimed are APD obtained by this process.

Abstract: Aqueous solutions of adhesive materials which can be easily filtered and deodorized, particularly for self-adhesive labels, with a solids content of over 65 % can be produced with good reproducibility of characteristics through copolymerization of esters of acrylic and/or methacrylic acid in the presence of less than 50 ppm inhibitor and preferably in the presence of 0.01 to 5 % by weight of reducing agents, according to a special emulsion process. The highly concentrated and steam-deodorized adhesive material dispersion is free of coagulants and specks.

Abstract: Production of aqueous polymer dispersions with low viscosity and a polymer volume concentration NOTLESS 50 vol.% comprises free radical emulsion polymerisation of ethylenically unsaturated monomers, except vinylidene halides, in the presence of initiator(s) and a starting polymer. Most of the monomers are emulsified in an aqueous dispersion of the starting polymer and this emulsion is transferred continuously to the polymerisation reaction.
