Abstract
Blends of polymers of vinyl acetate and polymers derived from acrylic acid have been discovered which exhibit thermodynamic miscibility. These polymer blends exhibit excellent mechanical compatibility, provide enhanced toughness and strength superior to the sum of the weight averaged properties of the constituent polymers and are useful in molding structures such as films and in compounded formulations such as coatings, emulsions and adhesives.
