Process for producing narrow polydispersity alkenylphenol polymer |
摘要 |
A process for producing a monodisperse polymer which has a number-average molecular weight from 1,000 to 100,000 and a molecular weight distribution Mw (weight-average molecular weight)/Mn (number-average molecular weight)=1.00 through 1.50 is disclosed. This process comprises: homopolymerizing or random copolymerizing an anionic polymerizable compound by living anionic polymerization using an organic alkali metal and/or an alkali metal as a polymerization initiator, wherein a target molecular weight is obtained by adding the compound divided into multiple steps.
