Tertiaryaminoalkyllithium initiators and the preparation thereof |
摘要 |
Relatively pure tertiaryaminoalkyllithium initiators suitable for anionic polymerization reactions are prepared at low temperatures in an organic ether by reacting an equivalent excess of lithium metal with a tertiaryaminoalkylhalide. The lithium initiators are very stable at moderate temperatures when the ether is replaced by an aliphatic, a cycloaliphatic, or an aromatic solvent. Yields of the initiator in excess of 98% are readily achieved.
