Process for the preparation of copolymers from ethylene and vinyl esters
Abstract
Abstract THIS INVENTION RELATES TO A PROCESS FOR THE PREPARATION OF COPOLYMERIZATES FROM ETHYLENE AND VINYL ESTERS AND POSSIBLY OTHER OLEFINICALLY UNSATURATED ORGANIC COMPOUNDS IN AN AQUEOUS EMULSION UTILIZING A REDOX POLYMERIZATION CATALYST SYSTEM COMPRISING INORGANIC AND/OR ORGANIC PERCOMPOUNDS, HYDROGEN AND A COLLOIDALLY DISPERSED NOBLE METAL OF THE VIII SUBGROUP OF THE PERIODIC TABLE WHEREIN THE POLYMERIZATION IS CONDUCTED AT PRESSURES UNDER 100 ATMOSPHERES AND SAID VINYL ESTER IS A VINYL ESTER OF A BRANCHED CHAIN MONOCARBOXYLIC ACID HAVING AT LEAST 9 CARBON ATOMS AND IS EMPLOYED IN AN AMOUNT OF FROM 10 MOL-PERCENT TO 80 MOL-PERCENT. THE INVENTION ALSO RELATES TO THE COPOLYMER SO PRODUCED WHICH HAS AN EXCELLENT COLD STABILITY AND ELASTICITY.
