Procedure

Then, to the resultant solution were dropwise added 5 g of maleic anhydride and 0.5 g of dicumyl peroxide over a period of 4 hours, followed by further heating for another 2 hours. Thereafter, the solution was allowed to stand for cooling and then introduced into acetone to obtain a propylene homopolymer graft-modified with maleic anhydride (i.e., the aforesaid component (c-1), hereinafter called "GPP-1" for short).
