ABSTRACT:
Rubbery polybutadiene containing at least 85 percent cis 1,4-addition can be made by polymerizing 1,3-butadiene with a catalyst formed from trialkylaluminum, for example, triethylaluminum, and titanium tetraiodide. The rubbery polybutadiene exhibits low hysteresis and is particularly useful in the manufacture of tires.
