Abstract
Butadiene is partially polymerized anionically in the presence of styrene to form a styrene-butadiene rubber of low styrene content. The resultant living polymer is terminated, butadiene removed, and optionally the styrene polymerized with or without additional styrene to form impact resistant styrene polymer.
