Abstract
Polymeric compositions are provided which include blends of polymers of vinyl acetate and polymers of propylene carbonate. These polymer blends exhibit excellent mechanical compatibility and are useful in molding structures, such as films, or in compounded formulations, such as emulsions and adhesives. These blends exhibit enhanced toughness superior to either of the constituent polymers alone.
