标题:Low temperature synthesis of condensation polymers
发明人：OGATA NAOYA
权利人:GOODYEAR TIRE & RUBBER
摘要:Condensation polymers of high molecular weight, such as polyesters, polyureas, and polyamides, are usually prepared at temperatures of 200° C. or greater. However, by utilizing the catalyst systems of the present invention, condensation polymers can be synthesized at much lower temperatures. The polycondensation catalyst systems of the present invention are particularly useful for synthesizing aliphatic polyesters, such as polyethylene terephthalate, from dicarboxylic acids and aliphatic glycols. The present invention more specifically discloses a process for the synthesis of an aliphatic polyester comprising polymerizing at least one dicarboxylic acid with at least one aliphatic glycol in the presence of (1) at least one phosphorus containing compound which contains at least one trivalent or pentavalent phosphorus atom which is bonded directly to at least one phenyl group, (2) an acid acceptor, and (3) at least one halogenated organic compound. It is preferred to utilize a polymeric agent having bound acid acceptor groups as the acid acceptor in the process of the present invention.

标 题:One pot synthesis of 5,10-dihydrophenazine compounds and 5,10-substituted dihydrophenazines
发明人：GIRI PUNAM; BYKER HARLAN J; BAUMANN KELVIN L
权利人:GENTEX CORP
摘要:Dihydrophenazines and bis(dihydrophenazines) are prepared in high yield under commercially viable reaction conditions by reacting a catechol with a 1,2-diaminoaryl compound, wherein either the catechol or the 1,2-diaminoaryl compound is provided in at least 50% molar stoichiometric excess. The product may be oxidized to the corresponding phenazine, but is preferably derivatized at one or both of the 5,10-positions to form a monosubstituted or disubstituted dihydrophenazine or bis(dihydrophenazine). Most preferably, 5,10-dialkyl-5,10-dihydrophenazines are prepared starting from catechol and 1,2-diaminoaryl compound in a one pot synthesis. The products are useful as dyes, and in particular as chromophores in electrochromic systems.
