Process for the production of impact resistant transparent polymers of vinyl chloride and acrylic acid ester
Abstract
Abstract A PROCESS FOR THE PRODUCTION OF IMPACT-RESISTANT AND WEATHER-RESISTANT POLYMERS OF VINYL CHLORIDE BY POLYMERIZATION OF VINYL CHLORIDE IN THE PRESENCE OF POLYMERS OF ACRYLIC ACID ESTERS. THE PROCESS COMPRISES POLYMERIZING VINYL CHLORIDE IN THE PRESENCE 2-10% BY WEIGHT OF A POLYMER OF 2-ETHYLHEXYLACRYLATE WITH AT LEAST 50% BY WEIGHT OF 2-ETHYLHEXYLACRYLATE SO THAT THE POLYMERIZATION OF THE VINYL CHLORIDE CONDUCTED AT TEMPERATURES OF FROM 50-65*C. WITH MIXING AT THE SATURATION PRESSURE OF THE VINYL CHLORIDE IN THE PRESENCE OF LIQUID VINYL CHLORIDE SUCH THAT THE CONVERSION AMOUNTS TO 70%. THE MAXIMUM MEAN PARTICLE DIAMETER AND THE MINIMUM MEAN PARTICLE DIAMETER OF THE POLYMER OF 2-ETHYLHEXYLACRYLATE IS REALTED TO THE CONCENTRATION OF THE POLYMER OF 2-ETHYLHEXYLACRYLATE IN THE POLYMER OF THE VINYL CHLORIDE.
