Abstract
Emulsion copolymers, for use as urea formaldehyde resin modifiers, are formed from vinyl chloride monomers, softening monomers, and functional monomers. The copolymer when blended with formaldehyde resins and used as a binder yields improved wet and dry tensile strength and better tear resistance. These binders are particularly useful as glass mat binders for the production of roofing shingles.
