  • Patent number: 5807977
    Abstract: This application is directed to novel fluorinated polymers and prepolymers derived from mono-substituted oxetane monomers having fluorinated alkoxymethylene side-chains and the method of making these compositions. The mono-substituted fluorinated oxetane monomers having fluorinated alkoxymethylene side-chains are prepared in high yield by the reaction of a fluorinated alkoxides with either 3-halomethyl-3-methyloxetane premonomers or aryl sulfonate derivative 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 scaleup is also disclosed. The fluorinated oxetane monomers of this invention can be readily homo/co-polymerized in the presence of a Lewis acid and polyhydroxy compounds to obtain hydroxy-terminated polyether prepolymers having fluorinated alkoxymethylene side chains.

  • Patent number: 5645848
    Abstract: A composition for delaying release of an active component into an aqueous fluid is taught which includes a capsule that swells in the presence of an aqueous fluid allowing moisture to enter the capsule into contact with a capsule decomposing agent activated by the entering moisture such that the agent decomposes the capsule sufficiently to release the active agent at a predetermined delayed time after the capsule contacts the aqueous fluid. A preferred capsule composition is gelatin and decomposing agents are a proteolytic enzyme or a salt that effects the osmotic gradient of the system. The controlled release composition of the invention is preferably utilized in a soft contact lens disinfecting system wherein a solution of hydrogen peroxide disinfects the lenses followed by neutralization of residual hydrogen peroxide wherein release of the neutralizing agent is delayed by means of the capsule proteolytic enzyme or salt composition.
