ABSTRACT:
Fast controlled wettability of glass fibers in a polymeric matrix is achieved by controlling the amount of unsaturation in the components of the chemical treatment present on the glass fibers. Glass fibers treated with an aqueous chemical treating composition having a polar thermoplastic film forming polymer, coupling agent and lubricant have these components with an amount of aliphatic unsaturation of less than 1.5 double bonds per mole of polymer or compound and a ratio of aliphatic unsaturation to aromatic unsaturation of not greater than 0.1. For the polar thermoplastic film forming polymer, the viscosity of the polymer is less than 10,000 centipoise and the aliphatic unsaturation can be controlled by limiting the amount of unsaturation on the monomer and also controlling the amount of solvent used in emulsifying the polymer in water. Also the components of the aqueous chemical treating composition have limited amounts of any component which is chain extension inducing or condensation reaction inducing.
