Abstract
Abstract An improved laminated structure comprised of two adjoining layers of synthetic resin laminated through a layer of a post-halogenated adhesive olefin resin of an alpha-olefin having 2 to 8 carbon atoms. The post-halogenated adhesive olefin resin has a halogen content of 0.1 to less than 10% by weight based on its own weight and a crystallinity, determined by the X-ray diffraction method, of 5 to 30%, and is obtained by the post-halogenation of an unhalogenated olefin resin having a crystallinity, determined by the X-ray diffraction method, of 10 to 45%.
