Abstract:
A curable composition which comprises:(A) a (meth)acrylic polymer having alkenyl groups at the chain ends prepared by the process comprising the steps of: (i) preparing a (meth) acrylic polymer having a chain end structure of formula (1) â€”CH2â€”C(R1)(CO2R2)(X)â€ƒâ€ƒ(1) wherein R1 is hydrogen or methyl; R2 is a C1-20 alkyl, C6-20 aryl or C7-20 aralkyl; X is chlorine, bromine or iodine;by polymerizing (meth) acrylate monomers using an organohalogenated compound or a halosulfonyl compound as an initiator and a metal complex catalyst wherein the central metal atom is selected from the group consisting of the elements of Groups 8, 9, 10 and 11 of the periodic table; and (ii) converting the halogen atom in the structure of formula (1) into an alkenyl group-containing substituent; and (B) a polyvalent hydrogensilicon compound.
