| 摘要 |
Organo-lithium compounds of the formula: <IMAGE> wherein R is an alkyl group of up to 5 carbon atoms, R' is either hydrogen or an alkyl group of up to 5 carbon atoms and n is an integer from 2 to 10. These bifunctional organo-lithium compounds are prepared without the use of any polar or complexing agent and are useful as polymerization initiators for the production of block copolymers.
