Process for making a dilithium initiator and the dilithium initiator so produced |
| abstract |
This invention concerns a process for making a dilithium initiator which comprises mixing together a di (1-{alkyl or aryl} ethylene) arene compound and diethylether and then adding the mixture to (a) a secondary lithium alkyl and/or (b) a tertiary lithium alkyl to allow the same to react at a temperature of from (a) 40 to 50 DEG C or (b) 25 to 50 DEG C such that the molar ratio of diethylether to lithium alkyl is from 0.1:1 to (a) 1.5:1 or (b) 2:1 and the molar ratio of di (1-{alkyl or aryl} ethylene) arene compound to lithium alkyl is from 0.4:1 to 0.6:1. It also concerns the use thereof in the preparation of anionically polymerized polymers. |
