    摘要： FILM FORMING COMPOSITIONS, WHICH GIVE HARD GLOSSY, WATER-DISPERSIBLE FILMS AND WHICH ARE PARTICULARLY USEFUL FOR COATING OR SATURATING FIBROUS SHEET MATERIAL SUCH AS PAPER AND WOVEN AND NON-WOVEN TEXTILES, ARE PREPARED BY COMPOUNDING (INTIMATELY MIXING), IN SOLUTION, 1 TO 5 PARTS BY WEIGHT OF A WATER-SOLUBLE PHOSPHATE ESTER SURFACTANT WITH 1 PART BY WEIGHT OF AN ALKYL VINYL EITHER POLYMER SELECTED FROM THE GROUP CONSISTING OF HOMOPOLYMERS OF ALKYL VINYL ETHERS IN WHICH THE ALKYL GROUPS, HVE FROM 1 TO 18 ALKYL CARBON ATOMS AND COPOLYMERS OF SUCH ALKYL VINYL ETHERS WITH EACH OTHER OR WITH MALEIC ANHYDRIDE. SUCH COMPOSITIONS WHEN APPLIED TO PAPER AND SIMILAR SHEET MATERIAL AS A COATING CAN SERVE BOTH AS A REMOISTENABLE ADHESIVE AND HEAT SEALABLE ADHESIVE. THEY CAN ALSO BE APPLIED TO PAPER ETC. EITHER AS A COATING OR SATURANT TO DECREASE THE POROSITY OF THE SHEET, INCREASE ITS STIFFNESS OR TENSILE STRENGTH. THE WATER SENSITIIVITY OF THE FILMS PRODUCED BY SUCH COMPSOITIONS MAY BE MODIFIED BY INCORPORATING A WOOD ROSIN ESTER (WHICH MAY BE EITHER HYDROGENATED OR UNHYDROGENATED) OR A HYDROCARBON RESIN IN THE COMPOSITION. VARIOUS OTHER ADDITIVES, SUCH AS PIGMENTS TO INCREASE THE OPACITY OF THE RESULTING FILMS, MAY ALSO BE INCORPORATED IN THE COMPOSITIONS.

    摘要： Beverages such as juices, vinegars, beers and wines are clarified and rendered haze-free by contacting the beverages with water-insoluble, water-swellable, crosslinked N-vinyllactam or Nalkyl-N-vinylamide polymers in the form of porous granules or beads. The granules or beads when spent are regenerated by an aqueous alkaline treatment.
