MONO-SUBSTITUTED FLUORINATED OXETANE MONOMERS

摘要

This application is directed to fluorinated oxetane monomers and methods for making the monomers. The mono-substituted fluorinated oxetane monomers having fluorinated alkoxymethylene side-chains are prepared in high yield by the reaction of fluorinated alkoxides with either 3-halomethyl-3-methyloxetane premonomers or aryl sulfonate derivatives of 3-hydroxymethyl-3-methyloxetane pre-monomers. Preparation of a mono-substituted 3-bromomethyl-3-methyloxetane premonomer via a simple, high yield process amenable to commercial scale-up is also disclosed. The fluorinated oxetane monomers are useful for the production of fluorinated prepolymers and elastomers which exhibit an improved contact angle for drops of water on a fluorinated oxetane elastomer as compared to a Teflon .TM. surface.
