Abstract
Abstract A rubber-reinforcing article is prepared by treating glass fibers with a saturated substituted mercapto or epoxy silane such as gamma mercaptopropyl trimethoxy silane or glycidoxypropyl trimethoxy silane and thereafter coated with an unsaturated elastomer in an uncured stage such as natural rubber, polychloroprene, butyl rubber, styrene-butadiene rubber, etc. The elastomer-coated fiber glass is then contacted with a matrix comprising a rubbery polymer containing at least one curing agent for the rubbery polymer and the composite is cured at elevated temperatures.
