摘要： This invention is directed to mono- and bis-substituted oxetane monomers having fluorinated alkoxymethylene side chains, hydroxy-terminated prepolymers derived from these mono- and bis-substituted oxetane monomers and tetrahydrofuran (THF), and polymers produced from these prepolymers, as well as the synthesis processes associated with each, and the use of the monomers, prepolymers and ultimate polymers, both directly and as components of numerous compositions.

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 premonomers. 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 TeflonTM surface.
