Abstract
Abstract The improvement in the bonding relationship between glass fibers and elastomeric materials in the manufacture of glass fiber reinforced elastomeric products wherein the individual glass fibers are sized and/or bundles of previously sized glass fibers impregnated with a composition containing a resinous material formed by the reaction of an aldehyde with phenolic compound having a mercapto or thio substituent in the meta or para positions.
