International Classification:

G02B006/10

US Classification:

385/002000, 385/129000

Abstract:

An electrooptic device and method for making the same, including one or more of substrate, a buffer layer, a charge dissipation layer, and electrodes. An F containing active trapping layer is deposited at the substrate/buffer interface, within the buffer layer, and/or on top of the buffer layer. The active F ions in the F containing active trapping layer react with positive ions, such as Li from the substrate to form stable compounds such as LiF. Porous material such as carbon nanotubes may be used in place of or in addition to the F containing active trapping layer. The reduced number of Li ions reduces the DC drift of the associated electrooptic device. The profile of the implanted ions may be adjusted to control and/or optimize the properties of the electrooptic device. Fluorine is particularly advantageous because it also lowers the dielectric constant thereby facilitating higher frequency operation.

Abstract:

Provided are selected types of terpolymer components comprising terpolymers having monomer units derived from ethylene (E), dicyclopentadiene (DCPD) and norbornene-based (NB) co-monomers. Such terpolymer components have certain specified amounts of each co-monomer as well as certain specified molecular weight and glass transition temperature characteristics. Terpolymer components which are derivatized by hydrogenation and/or by epoxidation and/or hydroxylation are also disclosed, as well as thermoplastic polyolefin compositions which contain the terpolymer components and which have especially desirable structural and thermal properties.Also provided are processes for preparing and derivatizing the terpolymer components herein. Such preparation processes comprise: a) contacting ethylene with a polymerization mixture comprising selected amounts of both DCPD and NB co-monomers, in the presence of a selected activated cyclopentadienyl-fluorenyl metallocene catalyst under specific polymerization conditions to thereby form the desired ethylene-dicyclopentadiene-norbornene terpolymer components within the polymerization mixture. These terpolymer components can then be subsequently derivatized by hydrogenation or functionalization of the residual double bonds therein.
