Alkene styrene polymers
Abstract
Abstract A LOW MOLECULAR WEIGHT ALKENE SUCH AS ETHYLENE IS COPOLYMERIZED WITH STYRENE BY A LOW PRESSURE EMULSION OR SUSPENSION POLYMERIZATION BY INCORPORATING A WATER SOLUBLE OLEFIN COMPLEXING AGENT IN THE AQUEOUS MEDIUM USED IN THE POLYMERIZATION. IN A TYPICAL EMBODIMENT, ETHYLENE IS CONTRACTED WITH AN AQUEOUS EMULSION OF STYRENE, A PEROXIDE CATALYST AND AN ETHYLENE COMPLEXING AGENT WHICH IS A WATER SOLUBLE SALT OF A MULTIVALENT METAL. THE POLYMERIZATION CAN BE PERFORMED AT MILD CONDITIONS OF TEMPERATURES FROM ABOUT 10* TO ABOUT 200*F. AND PRESSURES FROM ABOUT 10 TO ABOUTY 100 ATMOSPHERES. OTHER COMONOMERS CAN BE INCLUDED TO PREPARE TERPOLYMERS OF ETHYLENE, STYRENE AND DESIRED OTHER MONOMERS. THE PRODUCTS HAVE IMPROVED PROPERTIES OVER POLYSTYRENE.
