1,3-Butadiene → Benzene, ethenyl-, polymer with 1,3-butadiene

온도

88 °C

In this experiment, a styrene-butadiene polymer was synthesized utilizing the continuous polymerization procedure of this invention. A two-reactor system which consisted of a 1-gallon first reactor and a 2-gallon second reactor was utilized with the polymerization temperature being maintained at about 190° F. (88° C.). In the procedure used, 1,3-butadiene was charged into the first reactor at a rate of 115.2 grams per minute, n-butyl lithium was charged into the first reactor as a 0.25M solution at a rate of 1.6 grams per minute and TMEDA was charged into the first reactor as a 0.25M solution at a rate of 1.04 grams per minute. The 1,3-butadiene monomer was charged into the reactor as a 16 weight percent premix solution in hexane. The residence time in the first reactor was 0.51 hours.
