    • When producing a graft modified polyolefin by melting and kneading a polyolefin, a radical-polymerizable monomer and a radical-polymerization initiator, the producing efficiency is improved. The grafting reaction is effected by feeding the melted polyolefin containing either one of said radical-polymerizable monomer and the radical-polymerization initiator to the other. When said radical-polymerizable monomer is an unsaturated carboxylic anhydride, said unsaturated carboxylic anhydride as a starting material is preliminarily heated at 50.degree. to 250.degree. C., and then fed to the grafting reaction mentioned above. When the monomer is an unsaturated carboxylic acid or an acid anhydride of such an unsaturated carboxylic acid, an organic peroxide of a formula (I) is used as the radical-polymerization initiator. ##STR1## In this formula (I), two substituting groups connected directly to the benzene ring have an ortho-positional relationship or a meta-positional relationship, R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 and R.sub.6, which are the same as or different from one another, each denote a hydrogen atom or an alkyl group having the number of carbons of 1 to 10.
