  Vinyl unsaturated copolymers are described which are obtained in a two-step process and which consist of monomeric units A, B, C, D and E, copolymerized in a first step, and in a second step reacted with a reactive vinyl monomer Mv, and in which A is a silicon or fluorine containing vinyl monomer, 20-79.5% by weight; B is N,N-dimethylacrylamide, N-vinylpyrrolidone, or N-vinylacetamide, 20-79.5% by weight; C is an active hydrogen containing vinyl monomer, 0.5-25% by weight; D are other copolymerizable comonomers, 0-30% by weight, and E is a chain transfer agent, 0-10 mol percent. Mv is a vinyl unsaturated isocyanate. These vinyl unsaturated polymers are useful, either by themselves or in combination with other copolymerizable vinyl monomers, as heat or UV-curable coatings or glass, plastic, wood, paper, textiles, metal or ceramics, said coatings possessing low surface energies and low refractive indices. They are especially useful as UV-curable hydrophilic coatings and water-swelling biocompatible polymers, especially fully molded highly oxygen-permeable contact lenses.
