    摘要： The present application relates to polyester compositions, processes to prepare molded articles from these polyester compositions, and containers fabricated from polyester clay composites for food and beverages. The processing methods employed in this invention enable containers to be formed which exhibit excellent clarity. Specifically, the present invention relates to a process comprising forming a parison from a composite composition comprising about 0.10 to about 25 weight % platelet particles dispersed in at least one polyester at a processing temperature which is at least 50° above the Tg of said polyester; and molding said parison into a clear, thin walled article.

    摘要： This invention relates to a process for producing a polyester comprising the steps of: (g) obtaining an aqueous homogenous solution of isosorbide; (h) feeding the aqueous homogenous solution of step (a) into a reactor; (i) feeding one or more glycols and one or more dicarboxylic acids either into the aqueous solution of step (a) or into the reactor of step (b) either prior to, during and/or subsequent to step (b); (j) esterifying the reactor contents at sufficient temperatures and pressures, and optionally in the presence of suitable catalysts, to effect esterificaton; (k) forming a prepolymer; and (l) polycondensing the prepolymer at sufficient temperatures and pressures in the presence of a suitable catalyst to effect polycondensation to form a polyester.

    摘要： This invention relates to polyester polyesteramide blends comprising: (A) about 95-99.99 weight percent of a polyester which comprises a dicarboxylic acid component comprising repeat units from at least 85 mol % terephthalic acid, naphthalene-2,6-dicarboxylic acid or mixtures of terephthalic acid and naphthalene-2,6-dicarboxylic acid and a diol component comprising repeat units from at least 85 mol % ethylene glycol, said mole percents being based on 100 mol % dicarboxylic acid and at least 100 mol % diol; and (B) about 5-0.01 weight percent of a polyesteramide of the formula: A(N)x(D)y where A is a dicarboxylic acid selected from aromatic or cycloaliphatic dicarboxylic acids having 8 to 14 carbon atoms or aliphatic dicarboxylic acids having 3 to 24 carbon atoms, N is a diamine having 2 to 24 carbon atoms, D is a diol having 2 to 14 carbon atoms, X is an integer from 0.01 to 0.99 and Y is an integer from 0.99 to 0.01. The blends of the present invention display good barrier properties, low color and acetaldehyde concentration. The blends are useful for a variety of molded articles including containers, films and sheets.
