摘要： A process for producing a film-like or fibrous structure of an aromatic polyester, which comprises(1) forming an unstretched film-like or fibrous structure by melt-shaping a blend comprising 100 parts by weight of (A) an aromatic polyester having a high degree of polymerization derived from an aromatic dicarboxylic acid as a main acid component and an aliphatic diol and/or an alicyclic diol as a main glycol component and (B) 3 to 300 parts by weight of a low-molecular-weight compound being substantially non-reactive with the aromatic polyester (A) and having a boiling point of at least about 200.degree. C. under atmospheric pressure and a molecular weight of not more than 1,000,(2) stretching the resulting film-like or fibrous structure,(3) extracting at least a major portion of the low-molecular-weight compound from the stretched film-like or fibrous structure by using an organic solvent which does not substantially dissolve the aromatic polyester under the extracting conditions, and(4) if desired, heat-setting the film-like or fibrous structure after the stretching step (2) and/or the extracting step (3).The film-like or fibrous structure of an aromatic polyester prepared by the process substantially contains no low-molecular-weight compound or contains the low-molecular-weight compound in an amount of up to about 1 part by weight at most per 100 parts by weight of the aromatic polyester.

摘要： There is provided by this invention a process for the production of high molecular weight linear polyethylene terephthalate condensation polyesters which are useful especially for preparing specialty fibers which have excellent resistance to degradation so that they can be used in such commercial articles as paper making machine fabric, industrial belting, etc. The improved high molecular weight linear polyethylene terephthalate condensation polyester specialty fibers are characterized by improved hydrolytic stability and by reduction in the free carboxyl content so as to have a carboxyl concentration of less than about 6 gram equivalents per 10.sup.6 grams of the polyester. These polyester specialty fibers are prepared by the steps of adding an end capping reagent to particles of the said feed polymer, heating to obtain a homogeneous mixture of the said polyester and end capping reagent, mechanically working the polyester melt, and forming filaments of the linear polyester having a reduced free carboxyl content.
