Adhesive for chlorine-containing polymers and aromatic group-containing polymers

Claim 1

An adhesive for joining together two polymers to form a laminated structure comprising (A) a first layer of polymer selected from the group consisting of a chlorine-containing polymer and an aromatic polymer, (B) a second layer selected from the group consisting of a chlorine-containing polymer, an aromatic polymer and a polyolefin with (C) an adhesive layer therebetween, said adhesive comprising a modified olefin polymer composed of (a) a recurring monomer unit selected from the group consisting of ethylene and propylene, and (b) a recurring monomer unit represented by following formula: ##STR63## wherein R 1 and R 2 stand for a hydrogen atom or an alkyl group having up to 4 carbon atoms, each of k, l, m and n is 0 or 1, Z 1 , Z 2 , Z 3 and Z 4 stand for an oxygen atom or a divalent group comprising at least two elements selected from carbon, hydrogen, nitrogen and oxygen, X 1 stands for a monovalent group comprising at least two elements selected from carbon, hydrogen, nitrogen and oxygen or a blend of said modified olefin polymer with a polyolefin, wherein ##STR64## in said recurring monomer unit (b) is selected from the group consisting of ##STR65## and is present at a concentration of 59 to 267 millimoles per 100 g of the polymer, and said polymer having an intrinsic viscosity (η) measured at 135° C. in decalin as a solvent of 0.7 to 4 dl/g.
