Patent abstract
Disclosed is an anionic diinitiator prepared using a diisopropenyl benzene compound and an organo lithium compound having primary polymerization sites. The anionic diinitiators are prepared by admixing a diisopropenyl benzene compound with diethyl ether, ethylene, an organo lithium compound, and a solvent under reaction conditions sufficient to prepare a diinitiator having primary lithium alkyl reactive sites. The diinitiators are particularly useful in preparing block copolymers.
