<p>A CELLULOSIC PRODUCT AS PAPER COATING COMPOSITION IS DISCLOSED COMPRISING AQUEOUS-BASED SEMI-CRYSTALLINE VINYL ACETATE-ETHYLENE POLYMER EMULSIONS, CONTAINING CRYSTALLINE ETHYLENE SEGMENTS, WHICH ARE USEFUL FOR IMPARTING OIL, GREASE, SOLVENT, WATER, AND MOISTURE VAPOR RESISTANCE. THE POLYMER EMULSIONS ARE PREPARED VIA THE DIRECT AQUEOUS-BASED FREE REDICAL EMULSION POLYMERIZATION OF ETHYLENE WITH VARIOUS OTHER COMONOMERS. THE SEMI-CRYSTALLINE AQUEOUS-BASED POLYMER EMULSIONS OF THIS INVENTION HAVE A CRYSTALLINE MELTING POINT AND A CRYSTALLINE HEAT OF FUSION RANGING FROM 5 TO 100J/G. THE SEMI-CRYSTALLINE AQUEOUS-BASED EMULSION POLYMERS OF THIS INVENTION CAN BE USED DIRECTLY AS A PAPER OR PAPERBOARD COATING FOR IMPARTING OIL, GREASE, SOLVENT, WATER, AND MOISTURE VAPOR RESISTANCE. FURTHER, THE PRESENT INVENTION PROVIDES A REPULPABLE PAPER AND PAPERBOARD.</p> |
