Binder for glass fibers, glass fibers for olefin resin reinforcement, and process for producing olefin resin composition for fiber-reinforced molding
This invention provides a sizing composition for glass fibers useful in reinforcing an olefin resin, which comprises at least a) an acid-modified olefin resin which has been neutralized with an amine and b) an amino-containing silane coupling agent. The sizing composition makes it possible to firmly adhere an olefin resin as a matrix resin and the glass fibers with each other and hence, to provide a molding having excellent strength without occurrence of fuzzing on the resin pellets or the molding. This invention also provides glass fibers for olefin resin reinforcement and a production process of an olefin resin composition for fiber-reinforced moldings.
