POLYPROPYLENE RESIN COMPOSITION FOR BONDING

摘要

PURPOSE:To obtain the title composition, excellent in adhesive strength and suitable for bonding a polyolefin layer to a polar group-containing polymer layer, by thermally mixing a specific crystalline propylene copolymer with an OH group-containing polysiloxane. CONSTITUTION:The aimed composition obtained by thermally mixing (A) a crystalline propylene copolymer prepared by polymerizing an alkenylsilane (e.g., vinylsilane or allylsilane) and/or alkenylchlorosilane with propylene using a stereoregular catalyst (preferably titanium halide or organoaluminum compound) with (B) an OH group-containing polysiloxane.
