الإجراء التجريبي

The copolymerization of α-methylstyrene and butadiene was carried out in a one-gallon batch reactor equipped with an air-driven stirrer, nitrogen lines, water-cooled coils, a rupture and dump tank as well as a solenoid controller to protect against temperature surges. The reactor has been previously conditioned for anionic polymerization (purged with dry nitrogen). To this reactor was added 38.5 ml of 0.909 g/ml α-methyl-styrene solution in hexane and 800 grams of 17.5 percent Bd solution in hexane were added to give a 10/90 ratio of α-methyl styrene/butadiene. The initial concentration was determined by GC analysis to be 18.3 percent solids. The reactor contents were adjusted to the reaction temperature of 65° C. and were equilibrated.
