20020122647, Sep 5, 2002

Filed:

Dec 21, 2000

Appl. No.:

09/747068

Inventors:

Robert Blomquist - Whippany NJ, US
Jian Deng - Brooklyn NY, US
Lawrence Schacklette - Maplewood NJ, US
MacRae Maxfield - Teaneck NJ, US

International Classification:

G02B006/122

US Classification:

385/129000, 385/143000, 385/145000, 523/001000

Abstract:

A fluorinated polymerizable compound useful for fabricating planar optical devices includes at least one fluorinated alkylene or alkylene ether moiety and at least two terminal acrylate moieties, each terminal acrylate moiety being connected to one of the fluorinated alkylene or fluorinated alklene ether moieties by an ester linking group. The fluorinated polymerizable compounds, or macromers, of this invention are useful for forming optical components exhibiting a refractive index comparable to that of glass fiber waveguides, while also exhibiting very low absorption losses. Polymerizable compositions suitable for preparing optical components can be prepared by combining the macromers of the invention with a photoinitiator. Conventional optical monomers may also be employed, if desired.

Inventors:

Robert Blomquist - Whippany NJ, US
Jian Deng - Brooklyn NY, US

International Classification:

C08G073/24

US Classification:

528/401000

Abstract:

The present invention provides an energy curable composition including a compound having an aromatic or heteroaromatic moiety; at least two fluorinated alkylene, arylene or polyether moieties, each fluorinated alkylene, arylene or polyether moiety being linked to the aromatic or heteroaromatic moiety through an ether or thioether; and at least one ethylenically unsaturated moiety, each ethylenically unsaturated moiety being linked to one of the fluorinated alkylene, arylene or polyether moieties. The present invention also provides an energy curable composition including a compound having an isocyanurate moiety, three fluorinated alkylene, arylene, or polyether moieties linked to the isocyanurate moiety at the nitrogens of the isocyanurate, and at least one ethylenically unsaturated moiety linked to one of the fluorinated alkylene, arylene, or polyether moieties. The present invention further provides polymeric materials and optical devices made using these compositions.
