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.

摘要:The invention provides a metal alkoxide complex of Formula (I), wherein X, M, R1, R2, R3, m, n, y and z are as defined in the Description. The invention also provides a catalyst composition comprising the metal alkoxide complex and a hydroxy-containing compound, wherein the molar ratio of the metal alkoxide complex to the hydroxy-containing compound is 1:0.1-1000. The invention also provides a production method of poly-ε-caprolactone or polyactide, wherein an ε-caprolactone monomer or a lactide monomer is reacted in the presence of the metal alkoxide complex or catalyst composition to obtain poly-ε-caprolactone or polylactide. The metal alkoxide complex and the catalyst composition thereof can be used to catalyze the synthesis of poly-ε-caprolactone or polylactide with a high efficiency. The molecular weight of polycaprolactone or polylactide can be controlled by the molar ratio of the metal alkoxide complex and the hydroxy-containing compound, and is adjustable in the range of 1000-600,000, and wherein the molecular weight distribution is from 1.03 to 1.50.n n[X n-m M(OCR 1 R 2 R 3 ) m ] y .(organic solvent) z   (I)
