A process for the preparation of high purity norbornene alkyl silyl ether is disclosed and claimed. Specifically, a process for the preparation of industrial scale high purity norbornene methyl silyl ether is disclosed and claimed. The high purity monomers prepared in accordance with the process of this invention are useful in a variety of applications including but not limited to the preparation of high quality and high purity polynorbornenes having utility in a variety of electronic applications, among various other applications.

Process for the preparation of high purity norbornene silyl ethers

Embodiments in accordance with the present invention encompass a composition comprising one or more of polycyclic olefinic monomers of formula (I) and one or more monomers of formula (III) for forming anion exchange membrane optionally in combination with one or more monomers of formula (II). The composition undergoes mass vinyl addition polymerization either under thermal or photolytic conditions and can be formed into ionomers on a suitable membrane support. The membrane supports thus formed are suitable as anion exchange membranes for fabricating a variety of electrochemical devices, among others. More specifically, the ionomeric membranes are formed on a variety of supports which contains a variety of quaternized amino functionalized norbornene monomeric units which are lightly crosslinked (less than five mol %). The membranes so formed exhibit very high ionic conductivity of up to 280 mS/cm at 80° C. The electrochemical devices made in accordance of this invention are useful as fuel cells, gas separators, and the like.

Supported membranes by thermal and UV initiated mass polymerization

Embodiments in accordance with the present invention encompass a variety of polymers derived from polycyclic olefin monomers, such as hydrocarbon functionalized norbornenes. The polymers so formed function as ionomers and are suitable as anion exchange membrane for fabricating a variety of electrochemical devices, among others. More specifically, the ionomeric polymers used herein are derived from a variety of quaternized amino functionalized norbornene monomers and are lightly crosslinked (less than ten mol %). The membranes made therefrom exhibit very high ionic conductivity of up to 198 mS/cm at 80° C. This invention also relates to using an anion conducting solid polymer electrolyte as the ion conducting medium between the two electrodes and the ion conducting medium within the electrodes acting as the ionic conduit between electroactive material and electrolyte. The electrochemical devices made in accordance of this invention are useful as fuel cells, gas separators, and the like.

Polycyloolefinic polymers and anion exchange membranes derived therefrom

Embodiments in accordance with the present invention encompass compositions encompassing a procatalyst and a thermal or photoactivator along with one or more monomers which undergo vinyl addition polymerization when said composition is heated to a temperature from 50&#xb0; C. to 100&#xb0; C. to form a substantially transparent film. The monomers employed therein have a range of refractive index from 1.4 to 1.6 and thus these compositions can be tailored to form transparent films of varied refractive indices. Accordingly, compositions of this invention are useful in various opto-electronic applications, including as coatings, encapsulants, fillers, leveling agents, among others.
