Abstract
Prepolymers prepared by U.V. or .gamma. irradiation of an ethylenically unsaturated monomer or monomers until a predetermined but incomplete degree of polymerization has been achieved. Coatings formed by the U.V. or electron beam curing of such prepolymers are also comprehended.
Claims12
A process for the preparation of a prepolymer capable of being cured by ultra-violet or ionising radiation, comprising the steps of subjecting a mixture of a polymerizable ethylenically unsaturated monomer or a mixture of such monomers and a polymer selected from the group consisting of polyamides, polyesters including alkyl resins, polycarbonates, epoxy resins, polyvinylalcohols, polyvinylchlorides, polysilanes and polysiloxanes, to ultra-violet or ionising radiation, until a predetermined but incomplete degree of polymerisation is achieved;
- and removing the prepolymer so formed from the radiation.
