SIZES FOR GLASS FIBERS COMPRISING EMULSIFIED CLAD PARTICLES OF POLY(METHYL METHACRYLATE)

摘要

A coating composition for glass fibers comprising a film former of emulsified clad particles having a core of poly alkyl methacrylates and that includes at least 50 of methyl methacrylate and a cladding of a softer thermoplastic polymeric material having a Tg of 10.degree.C or less. A method of producing such emulsified coated particles also is disclosed, as well as glass fibers coated with such mixtures. The coating composition protects the glass fibers during subsequent operations.
