<p>PURPOSE:An adhesive, consisting of a halogenated polyolefin obtained by halogenating a specific polyolefin, having improved adhesive properties even under heating at a relatively low temperature though with a low chlorine content, and useful for chlorine-containing polymers or aromatic polymers. CONSTITUTION:An adhesive obtained from a halogenated polyolefin prepared by pulverizing a polyolefin having <=50% crystallinity, suspending the resultant fine granular polyolefin in an aqueous medium, and halogenating (preferably chlorinating) the resultant aqueous suspension of the fine granular polyolefin to give optimally 1-6wt% halogen content. The aimed adhesive is preferably used for bonding a chlorine-containing polymer, preferably polyvinylidene chloride or polyvinyl chloride, to a polyolefin or aromatic polymer, e.g. polystyrene, polyethylene terephthalate, polycarbonate or polyphenylene oxide, to the polyolefin.</p> |
