Abstract:
A vinyl polymer which has 1.2 to 4 terminal functional group per molecule and has a ratio of weight average molecular weight to number average molecular weight of less than 1.8 as determined by gel permeation chromatography,said terminal functional group being-an alkenyl group of the general formula (3), (4), (5), (6), or (7) shown belowH.sub.2 C.dbd.C(R.sup.4)--R.sup.5 -- (3)H.sub.2 C.dbd.C(R.sup.4)--R.sup.5 --O-- (4)H.sub.2 C.dbd.C(R.sup.4)--R.sup.5 --OC(O)-- (5)H.sub.2 C.dbd.C(R.sup.4)--R.sup.5 --C(O)O-- (6)H.sub.2 C.dbd.C(R.sup.4)--R.sup.5 --OC(O)O-- (7)wherein R.sup.4 represents a hydrogen atom or a methyl group and R.sup.5 represents a direct bond, or an alkylene group containing 1 to 20 carbon atoms, an arylene group containing 6 to 20 carbon atoms or an aralkylene group containing 7 to 20 carbon atoms, which may contain one or more ether bonds, with the proviso that R.sup.5 of the general formula (3) represents an alkylene group containing 1 to 20 carbon atoms, an arylene group containing 6 to 20 carbon atoms or an aralkylene group containing 7 to 20 carbon atoms, which may contain one or more ether bonds.
