Procedure

A series of 75/25 butadiene/styrene random copolymers were prepared according to Polymerization Recipe III by a continuous polymerization process using a reactor train consisting of a 3-pint, round bottomed glass reactor with stirring means, a 20 feet by 1/2 inch copper tube, and inlet for the 1,3-butadiene coupling adjuvant, a 65-ml. Kenics Static Mixer, a silicon tetrachloride inlet, a gear pump to move the polymer cement and to provide some mixing of the silicon tetrachloride coupling agent with the polymer cement, and a 425-ml Kenics Static Mixer.
