Abstract
Abstract The improvement in the bonding relationship between glass fibers and elastomeric materials in the manufacture of glass fiberreinforced elastomeric products wherein individual glass fibers are impregnated with a composition containing a terpolymer formed by the interpolymerization of butadiene, styrene and a monomeric material which can be an amino silane containing ethylenic unsaturation or an amide formed by the reaction of an amino silane with polymerizable mono- and dicarboxylic acids.
