    摘要: The present invention provides a linear polyolefin wherein one of the terminals of linear polypropylene or linear ethylene-propylene random copolymer is modified with a (meth)acrylic derivative unit or styrene derivative unit to give a substantially monodipersed system. The feature thereof consists in such a linear polyolefin in which the terminal of linear polypropylene or linear ethylene-propylene random copolymer obtained by living polymerization is modified with a (meth)acrylic derivative unit or styrene derivative unit. For the production thereof, there are used methacrylic acid chloride, acrylic acid chloride, ethylene glycol dimethacrylate, etc. as the (meth)acrylic derivative, and divinylbenzene, etc. as the styrene derivative.
