The invention relates to olefin branched macromonomers, olefin graft copolymers
and olefin resin compositions having the advantage of good compatibility with polyolefin
resins and good moldability and workability. The olefin branched macromonomer satisfies
the following (a) and (b):
- (a) its weight-average molecular weight (Mw) measured through gel permeation
chromatography (GPC) falls between 400 and 200000;
- (b) its vinyl content is at least 70 mol % of all the unsaturated groups
in the macromonomer.
