Abstract: A microencapsulated polyaddition catalyst comprises a capsule core, containing polyaddition catalyst, and an acrylic copolymer capsule shell, the acrylic copolymer comprising copolymerized units of an intermolecular anhydride of an ethylenically unsaturated C3-C12 carboxylic acid. The polyaddition catalyst is selected from acyclic tertiary amines, alicyclic tertiary amines, N-alkylimidazoles, phosphines and organic metal salts. It is suitable for catalysing the reaction of a polyol compound with a polyisocyanate compound. The polyaddition catalyst is released by a chemical stimulus, such as on contact with polyols or water, for example.

Abstract: An aqueous binder composition. The aqueous binder composition is obtainable by radically initiated polymerization of vinyl acetate and ethylene, in the presence of polyvinyl alcohol in an aqueous medium, wherein (a) 50 to 94 wt % of vinyl acetate, (b) 5 to 40 wt % of ethylene, (c) 0.2 to 5 wt % of acrylamide and/or methacrylamide, and (d) 0.2 to 5 wt % of maleic anhydride and/or maleic acid are copolymerized in the presence of a polyvinyl alcohol having a degree of hydrolysis of 80 to 99 mol %. The amounts in wt % are each based on the total weight of the comonomers and add up in each case to 100 wt %.
