A novel alkyl functionalized polyether was synthesized by combination of anionic ring-opening polymerization(AROP) and thiol-ene click reaction. Afterwards, its plasticizing and antistatic effects for PVC were investigated. Firstly, poly(allyl glycidyl ether)(PAGE) intermediate product was obtained via AROP by using allyl glycidyl ether as a monomer and t-BuOK as an initiator. Then, PAGE was used as a precursor and flexible alkyl groups were introduced by employing thiol-ene click reaction, and PAGEbutane target product was obtained finally. Nuclear magnetic resonance(NMR) and gel permeation chromatography(GPC) measurements verified that the structure of resultant polymer was consistent with the design, and the molecular weight of PAGE can be flexibly tailored by varying the feed ratio of monomer to initiator. The studies on the thermal properties suggest that with the incorporation of alkyl groups, the glass transition temperature(Tg) decreased accordingly, and the Tg for PAGEbutane was -74.97 ℃. PAGEbutane exhibit good thermal stability. PAGEbutane could improve the toughness of PVC obviously without sacrificing its strength. Meanwhile, it could effectively reduce the surface resistivity of PVC and act as an antistatic agent. As compared to bis(2-ethylhexyl) phthalate(DOP), PAGEbutane exhibited enhanced resistance to extraction and volatility. © 2021, Editorial Department of Chem. J. Chinese Universities.
