Abstract

An adhesive resin which is obtained by reacting a polyolefin resin (A) containing carboxy groups and / or derivatives of the groups with an amine compound having at least two amino groups. It has excellent adhesion to a fluororesin (C). A layered product excellent in chemical resistance and barrier properties can be easily obtained with the adhesive resin.

Description

field of invention [0001] The present invention relates to a kind of adhesive resin that uses polyolefin resin as the main component to glue fluororesin, (hereinafter, sometimes simply referred to as adhesive resin), a method of using the adhesive resin for bonding, A laminated product prepared by using the adhesive resin and the use of the laminated product. Background technique [0002] Fluorine resins such as homopolymers of tetrafluoroethylene (PTFE) and copolymers of tetrafluoroethylene and ethylene (ETFE) have weather resistance and flame retardancy, and also have excellent hydrocarbon resistance, alcohol resistance, etc. , so they are suitable for use as fuel pipes for automobiles, etc. However, the molding temperature of PTFE and ETFE is at least as high as 300°C, and the processability is poor. [0003] In order to solve the above problems, a terpolymer (fluororesin) prepared by copolymerization of tetrafluoroethylene, vinylidene fluoride and hexafluoropropylene (...
