NEW PROTECTIVE COLLOIDS IN LATICES WITH IMPROVED FILM FORMATION AT LOW TEMPERATURES

摘要

The present invention provides an emulsion polymerization process comprising polymerizing a monomer composition on the basis of ethylenically unsaturated monomers in the presence of water and of at least one protective colloid. The protective colloid is chosen so that the difference between the glass transition temperature and the minimum film formation temperature of the emulsion polymerized product is significantly increased compared to emulsion polymerization products produced with conventional protective colloids.
