Termination of anionic polymerization using hydrocarbon terminating agents |
摘要 |
This is an improvement upon a process which comprises anionically polymerizing monomers with an anionic polymerization initiator in a suitable solvent thereby creating a living polymer. The improvement comprises terminating the polymerization by the addition of a terminating agent selected from the group consisting of hydrocarbons containing a C-H group where the carbon is connected directly to a triply-bound carbon, hydrocarbons containing a C-H group where the carbon is connected directly to two doubly-bound carbons and hydrocarbons containing a C-H group where the carbon is connected directly to at least 2 aromatic rings, whereing none of said hydrocarbons contain additional aliphatic unsaturation.
