| Research Abstract |
2-(Halomethyl)acrylates were found to quantitatively terminate the stereospecific anionic polymerization of methyl methacrylate (MMA) to afford isotactic and syndiotactic poly(methyl methacrylate) possessing reactive carbon-carbon double bond at their terminal ends. This terminating reaction was applied to the isotactic specific anionic polymerization of MMA initiated by lithium enolate of methyl 2-methylpent-4-enoate, and undec-10-ene-1-thiol was added to the carbon-carbon double bond at terminal end via Michael addition with base catalyst. The resulting polymer, isotactic poly(methyl methacrylate) with allyl groups at both initial and terminal ends, was cyclized through ring closing metathesis reaction with 1st generation Grubbs' catalyst to afford cyclic isotactic poly(MMA), although oligomerization of macromonomer by intermolecular metathesis reaction occurred at the same time.
