Abstract
The present invention relates to a polymerizable composition, comprising a polymerizable monomer of formula (I), a copolymerizable UV-initiator, at least one copolymerizable (meth)acrylic monomer:R1—(OCH2CH2)n-L-OC(O)—CR2═CH2 Formula (I)wherein R1 is hydrogen or a C1-C6 alkyl group, n is an integer from 1 to 100, L is a single bond or a divalent linking group, preferably a single bond or a C1-6 alkylene group, and R2 is hydrogen or a CH3 group; and The invention also relates to a random copolymer obtained by reacting the polymerizable composition, a crosslinked product of the random copolymer and an adhesive composite material comprising the random copolymer or the crosslinked product on a substrate.
