ADHESIVE BLEND OF POLYOLEFINS AND GRAFTED BLOCK COPOLYMER OF POLYSTYRENE
摘要
Composition comprising a mixture of from about 30% to about 99.9% of a polyolefin base resin; from about 0.1% to about 50% of a graft polymerized block copolymer having polystyrene end blocks and an aliphatic middle block; from 0 to about 40% by weight of an elastomer different from the above components; and from 0 to about 30% by weight of a nonelastomeric second polyolefin made from different monomers from those of the polyolefin base resin. The composition can be used as an adhesive film or tie layer, optionally by coextrusion between layers to be joined. Coatings ant coated substrates are also disclosed.
