ABSTRACT:
The object of the present invention is to provide such a polyolefin that only the terminal of polypropylene or ethylene-propylene random copolymer is modified with a (meth)acrylic derivative unit to give a substantially monodipersed system. The feature thereof consists in such a polyolefin that the terminal of polypropylene or ethylene-propylene random copolymer obtained by living polymerization is modified with a (meth)acrylic derivative unit. As the (meth)acrylic derivative, there are used vinyl methacrylate, allyl methacrylate, trimethylsiloxyethyl methacrylate, 2-trimethylsiloxypropyl methacrylate, N, N-dimethylaminoethyl methacrylate, N,N-diethylaminoethyl methacrylate, glycidyl methacrylate, acrylic acid chloride and like.
