GLASS FIBER REINFORCED ELASTOMERS

摘要

This invention is addressed to the improvement in the bonding relationship between glass fibers and elastomeric materials with which the glass fibers are combined in the manufacture of glass fiber reinforced elastomeric products, wherein individual glass fibers are coated or bundles of glass fibers are impregnated with a composition containing a resorcinol-aldehyde resin component, an elastomer component and a terpolymer of acrylonitrile, butadiene and styrene. It has been found that the presence of the terpolymer significantly reduces the track of the treated glass fibers in the green or uncured state. The coated glass fibers may be subsequently treated with a dialkyl ester of phthalic acid.
