| abstract |
THE INVENTION RELATES TO A SIZING AGENT OF THE RESIN EMULSION TYPE (COLOPHAN) FOR PAPER MANUFACTURING. THE SIZING AGENT CONSISTS OF A REINFORCED RESIN, A PRODUCT OF PARTIAL OR TOTAL QUATERNIZATION OF A COPOLYMER OF WHICH AN ESSENTIAL MONOMER IS AN ALKYLAMINOALKYL ESTER OR AMIDE OF ACRYLIC ACID (METH), AND WATER. THIS SIZING AGENT EXERCISES VERY GOOD SIZING ACTION IN PAPER MANUFACTURING SYSTEMS WHERE THE PH, WATER HARDNESS AND TEMPERATURE ARE HIGH, IN WHICH CONVENTIONAL SIZING AGENTS OF THE ANIONIC RESIN EMULSION TYPE CANNOT ACT EFFECTIVELY. FIELD OF APPLICATION: PAPER INDUSTRY. |
