Polyester polycondensation with titanyl oxalate catalyst and a catalyst enhancer |
| abstract |
The present invention is based upon the discovery that nontitanyl oxalates can enhance thencatalytic functionality of titanyl oxalate catalysts. This invention provides anovel catalyticncomposition containing a titanyl oxalate catalyst and a metallic oxalate catalyst enhancernand optionally containing a metallic cocatalyst such as an antimony based catalyst, Ansynergistic relationship has been discovered between titanyl oxalate catalyst and the catalystnenhancer. A synergistic relationship has also been discovered between the titanyl oxalatencatalyst, catalyst enhancer and a metallic cocatalyst such as antimony oxide or antimonyntriacetate. Also provided is an improved process of producing polyester by thenpolycondensation of polyester forming reactants in the presence of a catalytically effectivenamount of a polycondensation catalyst, wherein the improvement comprises utilizing, as thenpolycondensation catalyst, the novel catalyst composition containing a titanyl oxalate suchnas lithium titanyl oxalate and a catalyst enhancer such as a nontitanyl metallic oxalate likenlithium oxalate and optionally containing a metallic catalyst such as antimony oxide ornantimony triacetate. The improved process produces an improved polyester having lowernacetaldehyde numbers and good color. The titanyl oxalate/catalyst enhancer compositionncan be used as a polycondensation catalyst in combination with other catalysts to achievensynergistic catalytic activity. Preferred is a combination of lithium titanyl oxalate,nLi 2 TiO(C 2 O 4 ) 2 , lithium oxalate, Li 2 (C 2 O 4 ) 2 with antimony oxide or antimony triacetate ornantimony trisglycoxide. |
