ABSTRACT:
This invention is concerned with coating Glass Fibers with size and is also concerned with the provision of an improved size composition for use in carrying out the coating step. We provide an aqueous size composition including a polymer dispersion of cationic character, at least 90% of the polymer being formed from units derived from vinyl acetate. The cationic character of the polymer dispersion is formed during preparation of the polymer dispersion by emulsion polymerization.
