Abstract:
A process for the preparation of a curable polymer composition comprising free radical polymerisation of a functional olefinically unsaturated monomer comprising a functional group which is selected from isocyanate groups, alkoxysilane groups, and activated â€”CHâ€” groups bonded to at least two electron-withdrawing groups, wherein the activated â€”CHâ€” groups are selected from the group consisting of: an acrylic group, an acetoacetate group, a malonate ester group, a 1,3-diketone and a cyanoacetate group and which is capable of reacting with a curing agent, in which process the polymerisation is carried out in the presence of a reactive diluent which is a liquid organic compound of viscosity less than 2 Pa.s (20 poise) at 25Â° C. having at least two functional groups which are substantially non-reactive with the functional olefinically unsaturated monomer and which are capable of reacting with the said curing agent so that the curable polymer and the reactive diluent are linked by the curing agent in the same polymer network.
