| titleOfInvention | CONTINUOUS PROCESS FOR THE PREPARATION OF ACRYLAMIDE COPOLYMERS AND TERPOLYMERS BY SOLUTION POLYMERIZATION |
| abstract | THE PRESENT INVENTION CONCERNS A CONTINUOUS PROCESS FOR PREPARING SOLID, STICKY AND PRACTICALLY HOMOGENOUS TERPOLYMERS OF ACRYLAMIDE, OF AN ALKALINE METAL SALT OF ACRYLIC ACID AND OF A HYDULROXYALKYL ACRYLATE, AS WELL AS EVOLUTION OF COPOLYMERS , OF (METH) ACRYLAMIDOALKYLSULPHONIC ACID OR METAL ALKALINE SALT OF THE SAME AND OF (METH) ACRYLAMIDE OR N-ALKYL (METH) ACRYLAMIDE. IN ACCORDANCE WITH THIS PROCEDURE, AN AQUEOUS SOLUTION OF MONOMERS, AT A SINGLE PHASE, AT A HIGH SOLID CONTENT, FROM TANK 1, IS HEATED QUICKLY (IN 4), FROM TANK 1, IMMEDIATELY BEFORE DEPOSITING A UNIFORM LAYER OF THE SAID SOLUTION AND OF POLYMERIZATION INITIATOR, FROM RESERVOIR 5 ON A MOVABLE SURFACE HAVING A SURFACE TEMPERATURE PRACTICALLY EQUAL, AT THE LOCATION OF THE DEPOSIT, TO THE POLYMERIZATION INITIATION TEMPERATURE. THE INVENTION ALLOWS ECONOMICALLY TO OBTAIN SOLID POLYMERS, PRACTICALLY HOMOGENOUS, OF LOW MOISTURE CONTENT, WHICH CAN BE USED IN PARTICULAR AS FILTRATION CONTROL AGENTS IN AQUEOUS DRILLING FLUIDS. |
