Abstract: The present invention relates to thermoplastic compositions having; high dimensional stability at high temperatures. In particular it is directed to polyester compositions containing mica for use in dual-ovenable trays and clear lids for hot food containers. According to one embodiment, the present invention is directed to a polyester composition comprising a polyester containing greater than about 2 to less than about 10 weight % of a mica filler. According to another embodiment of the present invention the mica containing polyester is prepared by the addition of the mica during polymerization, using a buffer to minimize diethylene glycol formation. According to another embodiment of the present invention, the polyester composition containing greater than 2 to less than 10 weight % mica also contains an additive package of impact modifier, nucleating agent and pigment in a concentration from about 5 weight % to 20 weight of the total composition. According to another embodiment of the present invention, the polyester composition containing mica is thermoformed into a container, such as a food tray.

Abstract: The invention provides a method of making a copolyester and a resulting copolyester fiber that has increased dyeability and dye retention properties while maintaining good physical properties for textile applications. The fiber may be formed from a mixture comprising terephthalic acid and its ester equivalent in combination with ethylene glycol, and to which is added about 2-4 mole percent of at least two dicarboxylic acids, or their anhydride or ester equivalents excluding terephthalic acid and its ester equivalent, and between about 100 to 700 ppm pentaerytoritol, both being based on the amount of the terephthalic acid and its ester equivalent The dicarboxylic acids and pentaerytliritol may be added before esterification, or after esterification and before polycondensation.
