Abstract
PURPOSE: The titled emulsion that is produced by the emulsion polymerization of an ethylenically unsaturated monomer in the presence of a cationic group-modified polyvinyl alcohol, thus being used as a paper strength increaser because of its high stability, economic efficiency, and high adhesion to pulp and construction materials.
CONSTITUTION: In the presence of (A) a cationic group-modified polyvinyl alcohol such as a modified polyvinyl alcohol containing a copolymerization unit of formula I (B is formula II or III), the emulsion polymerization of (B) an ethylenically unsaturated monomer such as a mixture of vinyl acetate and acrylic ester is conducted in an aqueous medium at 30W120°C, preferably 40W90°C to produce the objective emulsion. The amount of component A used is preferably 0.01W20pts.wt. per 100pts. of component B.
