摘要：

We report on the first examples of the free radical polymerization of a fluorinated 2-vinylcyclopropane 2 and its copolymerization with an alkyl 2-vinylcyclopropane 2 in aqueous solution via their host-guest complexation with a random methylated beta-cyclodextrin (RAMEB) using a water-soluble initiator (VA50). Upon polymerization, the dethreaded cyclodextrin remained in water-solution, whereas the water-insoluble polymer precipitated out and was isolated. The polymers prepared exhibited mesophase behavior over a wide range of prepared exhibited mesophase behavior over a wide range of temperature. Both T-g and T-i of the copolymers increased linearly with the amount of fluorinated co-units.
