    摘要: Disclosed is a process for the preparation of a poly-(meth)acrylate ester, which comprises, upon polymerization of a (meth)acrylate ester by using an organometallic compound ((C.sub.5 Me.sub.5).sub.2 SmMe(thf) or the like) having at least one polymerization initiating site, carrying out the polymerization in the presence of a compound (acetophenone, 4-methyl-2-pentanone or the like), which contains in the molecule thereof a reactive hydrogen atom, as a chain transfer agent. The above-described process makes it possible to control the molecular weight easily, reduce the using amount of the organometallic compound, prevent the coloring of the poly(meth)acrylate ester and improve thermal decomposition resistance.

    摘要: One object of the present invention is to provide an unchlorinated type modified polyolefin resin which has excellent adhesion properties to a substrate comprising a resin having a low- or non-polarity and exhibiting hardly adherable properties, such as a polyolefin type resin, has an excellent solubility in a solvent, and has an excellent water resistance. The present invention provides a modified polyolefin resin produced by subjecting a polyolefin resin (A) to a graft modification by vinyl monomer(s) (B) comprising at least one (meth)acrylate monomer (b) in which an acryloyloxy group or methacryloyloxy group is bonded to a secondary carbon atom or tertiary carbon atom.
