Abstract:
The present invention provides methods and systems for continuous polymerization of ethylenically unsaturated monomers in a water-in-oil inverse emulsion under adiabatic conditions without the need for external cooling during the polymerization. The method comprises neutralizing a monomer composition comprising at least one acidic vinyl monomer with a base in an aqueous medium comprising water and water ice to form an aqueous monomer solution therefrom; homogenizing and degassing to form an inverse monomer emulsion; initiating polymerization; passing the inverse emulsion through a tube reactor without cooling, and flash evaporating a portion of the water from inverse emulsion to cool and concentrate the resulting polymer-containing inverse emulsion. During neutralization, the aqueous medium comprises an amount of water ice sufficient to maintain a temperature of 30° C. or less, and the polymerization is initiated by adding a free-radical polymerization initiator to the emulsion prior to passing the emulsion through the tube reactor.

Claim (Index 13):
The method of  claim 10 , wherein the thermal initiator and the oxidizing agent of the redox initiator pair are added to the aqueous monomer solution and oil phase prior to the homogenizing and degassing, and the reducing agent is added to the inverse emulsion after homogenizing and degassing, and before the passing of the monomer solution through the tube reactor.
