摘要： An aqueous copolymer adhesive dispersion having a long pot life and giving highly waterproof bonds, comprising an acid hardener of water-soluble acids having pKs of under 0 and an aqueous dispersion of a pre-crosslinked polyvinyl ester grafted onto polyvinyl alcohol, said polyvinyl ester being an ester of an acid of 1 to 12 carbon atoms and said pre-crosslinking caused by the presence of small amounts of poly-ethylenically-unsaturated compounds in the monomer mixture, as well as the aqueous dispersion and the method for its production.
