PURPOSE: A composition that is composed of a modified polyolefin, a powder of inorganic substance and an unmodified polyolefin, thus showing high adhesion to a variety of base materials, and the laminatings made by use of the composition. n CONSTITUTION: The objective composition is composed of (A) 10W80wt% of a modified polyolefin which is prepared by heating a polyolefin resin and an unsaturated compound bearing polar groups, preferably an organic silane in the presence of an organic peroxide, (B) 5W50wt% of a power of inorganic substance and (C) 10W80wt% of an unmodified polyolefin resin. As a polyolefin resin, is preferably a crystalline propylene polymer of 0.5W10g/10min melt flow rate. The same kind of polymer is used as components A and C. n COPYRIGHT: (C)1984,JPO&Japio |
