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 C.sub.3-C.sub.12 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.
