权利人:GOODYEAR TIRE & RUBBER
摘要:This invention disclosed a process for the synthesis of polyesteramides. By utilizing the phosphorus containing catalyst systems of the present invention, such polyesteramides can be synthesized at relatively low temperatures. The present invention specifically discloses a process for the synthesis of a polyesteramide which comprises polymerizing at least one diamine, at least one diol, and at least one dicarboxylic acid in the presence of (1) at least one acid acceptor; (2) at least one halogenated organic compound; and (3) at least one phosphorus containing compound selected from the group consisting of (a) triphenylphosphine, (b) triphenylphosphine oxide, (c) triphenylphosphine sulfide, (d) polymeric agents having pendant diphenylphosphine groups, (e) silicon-phosphorus compositions which contain at least one divalent oxygen atom which is bonded directly to a tetravalent silicon atom and a trivalent or pentavalent phosphorus atom; (f) compounds with the structural formula (C 6 H 5 ) 3 P=N-R, wherein R is a hydrogen atom or an alkyl group containing from 1 to 10 carbon atoms; and (g) compounds with the structural formula (C 6 H 5 )PR 1 R 2 wherein R 1 and R 2 can be the same or different, wherein R 1 is selected from the group consisting of alkyl groups containing from 1 to 10 carbon atoms and phenyl groups, and wherein R 2 is an alkyl group containing from 1 to 10 carbon atoms.

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.
