Radiation - crosslinkable copolymers - by copolymer of monomers contg vinylene-carbonyl /carbonyl vinylene or vinylene-carbonyl-vinyl

摘要

(a) 8-30 wt.% w.r.t. total monomers of olefinically unsatd. monomers contg. a (meth)acryloyloxy residue bonded directly or via an alkylenexy residue contg. >=2 C-atoms (which may be interrupted by >=1 O-atoms) to a (opt. halogen-, alkyl-, aryl- or alkoxy-substd.) benzene nucleus carrying an alkoxycarbonylvinylene grp., or via a vinylenecarbonyl-, carbonylvinylene- or vinylenecarbonylene reside to a (opt. halogen-, alkyl-, aryl- or alkoxy-substd.) benzene or naphthalene nucleus; are copolymd. in homogeneous phase, with (b) 92-70 wt.% of >=1 monomer H2C=C(R)-X, (where X is COOR, halogen, CN, (substd.) aryl, acyl, (substd.) alkene; R is alkyl, aryl, aralkyl, alkaryl. Products may be used as light sensitive coatings, in the printing industry.
