Abstract:
1. A radiation crosslinkable composition comprising copolymers of the formula in which (A) are identical or different and have the formula (II) (B) are identical or different and have the formula and (C) are identical or different and have the formula where X each individually is an alkylene radical having 1 to 700 carbon atoms optionally substituted by fluorine, chlorine, C Y each individually is a divalent hydrocarbon radical which has 1 to 30 carbon atoms and in which non-adjacent methylene units are optionally replaced by groups —O—, or is the radical —(CH Z each individually is a divalent hydrocarbon radical which has 1 to 30 carbon atoms and is unsubstituted or substituted by fluorine or chlorine, D each individually is a hydrogen atom or a monovalent, unsubstituted or substituted hydrocarbon radical, E each individually is an oxygen atom or an amino group —ND-, R each individually is a monovalent hydrocarbon radical which has 1 to 20 carbon atoms and is unsubstituted or substituted by fluorine or chlorine, R R R G each individually is as defined for Z, R″ is a hydrogen atom or a radical —CO—NH—Z—NCO, R′ if R″ is a hydrogen atom, is a radical HND-Y—Si(OR n each individually is an integer from 1 to 4000, o each individually is 0, 1 or 2, q is 0, 1 or 2, a is an integer of at least 1, b is 0 or an integer of at least 1, c is 0 or an integer of at least 1, with the proviso that in the molecule there is at least one radical R 5 , and the individual blocks (A), (B) and (C) are distributed in any sequence in the polymer. ii) optionally, at least one crosslinker bearing ethylenic unsaturation, iii) a photopolymerization initiator, iv) optionally, one or more fillers, v) optionally, one or more adhesion promoters vi) optionally, one or more of plasticizers, stabilizers, antioxidants, flame retardants, light stabilizers, and pigments, vii) optionally, crosslinkable polymers different from (i), and viii) optionally, one or more polymerization inhibitors.
