摘要： PROBLEM TO BE SOLVED: To prepare an adhesive which retains a practical adhesion strength at the ordinary temperature, after treated at a high temperature, and simultaneously has such excellent heat-resistant adhesivity under high temperature as capable of preventing the interlayer peeling of a laminate, when a severe treatment such as a high temperature charging treatment or a high temperature retort treatment is carried out. SOLUTION: This adhesive for forming laminates comprises a vinylic compound-modified olefinic polymer which is obtained by continuously graft- polymerizing a vinylic monomer to an olefinic polymer having a specific intrinsic viscosity and a specified Mw/Mn by a bulk polymerization method, a bulk suspension polymerization method or a solution polymerization method in a plug flow type reactor. The laminate is obtained by laminating an adhesive layer comprising the adhesive to a resin layer comprising a polyamide, a polycarbonate or a polyester. The laminate has two or more layers having a structure wherein the resin layer and the adhesive layer are adjacently laminated. A packaging material for retort pouches and hot film packages comprises the above laminate.

摘要： PROBLEM TO BE SOLVED: To obtain a polymer composition having an epoxy compound introduced therein at a high reaction efficiency and excellent in e.g. compatibility with a polar resin and adhesiveness thereto.
SOLUTION: A polyolefin (a-1) is obtained by polymerizing one or more kinds of olefins selected from ethylene and 3-20C α-olefins. An acid-modified polyolefin (A) is obtained by subjecting the polyolefin (a-1) to graft polymerization with at least one kind of ethylenically unsaturated carboxylic acid or its derivative (a-2). A first polymer composition is obtained by melting and mixing the acid-modified polyolefin (A) with a polyfunctional aliphatic epoxy compound (B). A second polymer composition is obtained by melting and mixing the polyolefin (a-1), at least one kind of ethylenically unsaturated carboxylic acid or its derivative (a-2), and a polyfunctional aliphatic epoxy compound (B).
