Abstract (en)
[origin: EP1900756A1] A method for the production of aqueous polymer dispersions by radical emulsion copolymerisation of 4-40C alkenes with unsaturated carboxylate esters in presence of a macromolecular host compound with a hydrophobic cavity and a hydrophilic shell, involves putting at least 50 wt.% of the host compound, at least 50 wt.% of the alkene monomer and optionally up to 10 wt.% of the other comonomer(s) in the reactor before initiating polymerisation and adding the rest during polymerisation. A method for the production of aqueous polymer dispersions (I) by emulsion polymerisation of unsaturated monomers in presence of dispersants, radical initiators and water-soluble macromolecular host compounds, using a monomer mixture comprising (A) 1-50 wt.% 4-40C alkene, (B) 50-99 wt.% 1-12C alkyl ester of a 3-6C alpha ,beta -mono-unsaturated mono- or di-carboxylic acid, (C) 0-10 wt.% 3-6C mono-unsaturated mono- or di-carboxylic acid and/or amide and (D) 0-25 wt.% other unsaturated monomers, and using a host compound (II) with a hydrophobic cavity and a hydrophilic shell in amounts of 0.1-20 wt.% based on total monomer content. In this method, at least 50 wt.% of compound (II), at least 50 wt.% of the total amount of monomer (A) and optionally up to 10 wt.% of each of the monomers (B)-(D) are put into the reactor before initiation and the rest of (II) and/or (A) is/are added under polymerisation conditions, plus the rest or all of (B)-(D). Independent claims are also included for (1) aqueous polymer dispersions (I) obtained by this method (2) adhesives and contact adhesives containing (I) (3) substrates coated with these adhesives .
