    • 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.

    • 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.
    • 本发明的一个目的是提供一种非离子型改性聚烯烃树脂,其对包含具有低或非极性并且几乎不具有粘合性的树脂的基材具有优异的粘附性,例如聚烯烃类树脂具有优异的 在溶剂中的溶解性,并且具有优异的耐水性。 本发明提供一种改性聚烯烃树脂,其通过使含有丙烯酰氧基或甲基丙烯酰氧基的至少一种(甲基)丙烯酸酯单体(b)的乙烯基单体(B)进行接枝改性而得到聚烯烃树脂(A) 键合到仲碳原子或叔碳原子上。
