  • Sizing composition and sized glass fibers and process
    Patent number: 4341877
    Abstract: A sizing composition for use in a process of producing sized glass fiber strands that can be used in reinforcing polymers is provided. Also provided are the sized glass fiber strands, glass fiber reinforced polymers and processes for producing these materials. The sizing composition comprises one or more organo silane coupling agents, a major amount of the solids of the aqueous sizing composition is an epoxidized polar thermoplastic copolymer where there are three to about twelve parts of epoxy per 100 parts of the other comonomer and one or more nonionic, cationic or anionic lubricants. The sizing composition can also have one or more compatibilizing agents such as a polyvinyl-acetate-ethylene copolymer unsaturated polyester resins, polyvinylacetate homopolymer, epoxy polymers and epoxy polyester copolymers. The comonomers for the epoxidized polar thermoplastic copolymer are vinyl acetate, acrylates, polyurethane condensate monomer, polyester condensate monomer, and polyamide condensate monomer.
