Abstract

PURPOSE: To obtain a modified polypropylene composition containing an unsaturated carboxylic acid in a low graft amount as having good adhesiveness, by a method wherein a low-density polyethylene is mixed in a modified polypropylene obtained by a melt kneading process and the resulting compound is heat treated.
CONSTITUTION: 90W50pts.wt. modified polypropylene obtained by melting and kneading a mixture comprising polypropylene, an unsaturated carboxylic acid or a derivative thereof and an org. peroxide is mixed with 10W50pts.wt. low- density polyethylene. The resulting mixture is heat treated at 60°C or higher, pref., 100°C or higher. As the unsaturated carboxylic acid to be used, maleic anhydride is most pref. The heat treatment is desirably carried out by heating and degassing said modified polypropylene so as to adjust an amount of an unreacted monomer therein to 0.05mol or less. As the low density polyethylene, one with an MF of 10.5W30g/min and a specific gravity of 0.914W0.940 is preferred.
