  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 to 250°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.    In this formula (I), two substituting groups connected directly to the benzene ring have an ortho-positional relationship or a meta-positional relationship, R₁, R₂, R₃, R₄, R₅ and R₆ ,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.

  通过熔化和捏合聚烯烃、可自由基聚合的单体和自由基聚合引发剂来生产接枝改性聚烯烃，可提高生产效率。接枝反应是通过将含有所述可自由基聚合单体和自由基聚合引发剂中的任一种的熔融聚烯烃喂入另一种聚烯烃来实现的。当所述可自由基聚合单体为不饱和羧酸酐时，将所述不饱和羧酸酐作为起始原料在 50 至 250°C 下初步加热，然后送入上述接枝反应中。当单体为不饱和羧酸或不饱和羧酸的酸酐时，使用式（I）的有机过氧化物作为自由基聚合引发剂。 在该式（I）中，与苯环直接相连的两个取代基具有正交位置关系或偏交位置关系，R₁、R₂、R₃、R₄、R₅ 和 R₆（它们彼此相同或不同）分别表示氢原子或碳原子数为 1 至 10 的烷基。
