실험 절차

A butadiene-styrene-hydroxyethyl acrylate polymer was prepared by conventional free radical emulsion polymerization techniques using a mixed fatty acid -- rosin acid soap, a ferrous-formaldehyde-sulfoxalate activator, an organic hydroperoxide catalyst and a thiocarbamate shortstop. The polymerization temperature was 5° C. One part by weight of hydroxyethyl acrylate was present initially, a further one part was added at 20% conversion and a further one part was added at 40% conversion. The polymerization was stopped at 62% conversion after 6.5 hours polymerization time. The recovered polymer contained about 2.9 weight percent of hydroxyethyl acrylate and had a Mooney (ML-4 at 100 C) of about 60.
