A process for the preparation of a variety of high purity norbornene alkanol monomers and their derivatives is disclosed and claimed. Specifically, a process for the preparation of industrial scale high purity norbornene methanol and its silyl ether derivative 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 alkanols and derivatives thereof

Embodiments of the present invention are directed generally to methods for producing high purity exo-alkenylnorbornenes from a mixture of conformational isomers thereof.

Process for producing high purity exo-alkenylnorbornene

Embodiments in accordance with the present invention provide alicyclic diepoxide compounds and methods for forming such compounds. Such methods encompass charging a reaction vessel with an appropriate diene and an appropriate dienophile and causing such to react to form and recover a desired alicyclic diepoxide precursor where such precursor is subsequently epoxidized. Such compounds encompass alicyclic diepoxides having purities of at least 95 percent or at least 98 percent with respect non-isomeric residues and are essentially free of any isomeric alicyclic diepoxide residues.

Preparation of alicyclic diepoxides

Embodiments in accordance with the present invention provide for forming essentially pure diastereomers of 5/6-substituted norbornene-type monomers. Further, embodiments in accordance with the present invention encompass polymerizing such diastereomers to form addition or ROMP polymers where a desired exo-/endo-ratio of the diastereomers is provided to the polymerization, such ratio designed to provide a desired ratio of endo-/exo-structured repeating units for a resulting polymer to have desired physical or chemical properties.
