Synthesis of methacryloyl-PMA macromonomer via SARA ATRP using a Janus initiator |
| 초록 |
This work presents a simple method for preparation of methacryloyl-poly(methyl acrylate) macromonomer via supplemental activator and reducing agent atom transfer radical polymerization (SARA ATRP) and sulfoxide elimination reaction. We synthesized a Janus initiator initiator which is sulfoxide protected at the α-end with bromo group at the ω-end. While alkyl bromide can participate as the initiator in an ATRP process, sulfoxide protected (SP) methacryloyl can be de-protected to generate vinyl group by simply heating. Kinetic study for the sulfoxide group elimination in the SP-initiator was studied with respect to temperature in terms of 1H NMR spectroscopy. In order to prohibit de-protection of the sulfoxide group, low temperature was maintained throughout the polymerization and purification. The vinyl group functionality of the macromonomer was confirmed as more than 98% indicating the efficient nature of the protection-deprotection method to generate macromonomer. |
