| abstract |
The invention relates to an isocyanate group-containing copolymer and to the preparation thereof. The isocyanate group-containing copolymer contains, in copolymerised form, from 5 to 60% by weight of an N-(1-alkenyl) isocyanate and from 95 to 40% by weight of at least one (meth)acrylate, some of which may be replaced by further copolymerisable, olefinically unsaturated compounds containing no OH-, CH-, NH- or SH-acidic groups, and has a mean molecular weight of from 500 to 10000. The copolymer is prepared by photopolymerisation. |
