摘要： Polyesters whose polycondensation is catalyzed by titanium- containing catalysts and which are susceptible to acetaldehyde formation during polycondensation or subsequent molding operations are prepared with low finished acetaldehyde content and reduced acetaidehyde generation by adding an ammonium or amine salt of an oxyphosphorus- acid. Polyesters, especially polyethylene terephthalate, may be produced with high inherent viscosity in reduced processing time, without the necessity of further polymerization in the solid state.

摘要： A method for the production of solid polyester polymer particles comprising: a) polycondensing a molten polyester polymer composition in the presence of a polycondensation catalyst composition comprising antimony species; b) continuing the polycondensation of the molten polyester polymer composition to an It.V. of 0.68 dL/g or more; and c) after reaching an It.V. of 0.68 dL/g or more, adding a catalyst stabilizer or deactivator to the polymer melt; and d) after reaching an It.V. of 0.68 dl_/g or more, solidifying the melt into solid polyester polymer particles which do not contain organic acetaldehyde scavengers. In a further embodiment, after solidification of the polyester from the melt phase polycondensation process: e) the amount of residual acetaldehyde in the particles in the solid state is reduced to a level of 10 ppm or less without increasing the It.V. of the particles by more than 0.03 dl_/g. Such particles having an AA (acetaldehyde) generation rate of 20 ppm or less upon being melted after solidification following the melt phase production and a free AA level reduced after melt phase production to 10 ppm or less are introduced into a melt processing zone to make articles such as bottle preforms having acceptable levels of residual AA.

摘要： A process for thermally crystallizing a polyester polymer by introducing pellets into a liquid medium having a temperature of at least 140°C within a liquid medium zone and crystallizing the submerged pellets at or above the vapor pressure of the liquid medium without increasing the molecular weight of the pellets, and while the pressure on at least a portion of the pellets is equal to or greater than the vapor pressure of the liquid medium, separating at least a portion of said pellets and at least a portion of the liquid medium from each other. The crystallization is desirably conducted in the liquid medium zone without mechanically induced agitation. Optionally, the pellets are formed by an underfluid pelletizer. There is also provided a process for thermally crystallizing solid pellets in a pipe by directing a flow of solid pellets in a liquid medium through a pipe having an aspect ratio L/D of at least 50:1, wherein the solid pellets are crystallized in the pipe at a liquid medium temperature greater than the T g of the polyester polymer.
