Abstract
Abstract This invention is addressed to the treatment of glass fibers for use as reinforcement with elastomeric materials, and particular compositions used in the treatment of glass fibers, wherein the composition contains a resorcinol-aldehyde resin, an incompatible wax and a graft polymer formed of a monomer of vinyl chloride, vinylidene chloride, chloroprene and combinations thereof grafted onto a vinyl pyridine-butadiene-styrene terpolymer backbone.
