Filed:

Feb 27, 2004

Appl. No.:

10/789781

Inventors:

Sheldon Shafer - Clifton Park NY, US
Julia Lee - Niskayuna NY, US

Assignee:

General Electric Company - Schenectady NY

International Classification:

C08G 64/00

US Classification:

528196, 2641761, 264219, 502150, 528198

Abstract:

Liquid crystal polycarbonates are made by forming a reaction mixture containing (a) an activated diaryl carbonate; (b) at least two species of aromatic diols selected from among resorcinol, 4,4′-biphenol, hydroquinone, methylhydroquinone, 4,4′-dihydroxyphenylether, dihydroxynaphthalene, including in particular the 2,6, 1,5, and 2,7 isomers, 4,4′-dihydroxybenzophenone and 2,6-dihydroxyanthraquinone (anthraflavic acid); and (c) optionally bisphenol A in a maximum amount of 10 mole %; and processing the reaction mixture in a melt transesterification reaction to form a liquid crystal polycarbonate. While the product composition has the same overall characteristics as compositions made using diphenyl carbonate as the donor moiety for the carbonate linkage, they are analytically distinguishable because of limited incorporation of intermediate or end-cap residues derived from the activated diaryl carbonate.

Abstract:

In accordance with one aspect, the present invention provides an amino-siloxane composition comprising at least one of structures I, II, III, IV or V said compositions being useful for the capture of carbon dioxide from gas streams such as power plant flue gases. In addition, the present invention provides methods of preparing the amino-siloxane compositions are provided. Also provided are methods for reducing the amount of carbon dioxide in a process stream employing the amino-siloxane compositions of the invention as species which react with carbon dioxide to form an adduct with carbon dioxide. The reaction of the amino-siloxane compositions provided by the present invention with carbon dioxide is reversible and thus, the method provides for multicycle use of said compositions.
