ABSTRACT:
The invention relates to a copolyester containing (a) a dicarboxylic acid component having from about 80 to 100 mole % terephthalic acid or the ester thereof; less than or equal to 20 mole % of an aromatic dicarboxylic acid having up to 20 carbon atoms or the ester thereof; and less than or equal to 10 mole % of an aliphatic dicarboxylic acid or an ester thereof having up to 16 carbon atoms; and (b) a glycol component having from about 25 to 85 mole % 2,2,4,4-tetramethyl-1,3-cyclobutanediol, from about 15 to 75 mole % ethylene glycol; and less than or equal to 10 mole % of a diol having 3 to 16 carbon atoms, wherein the total mole % of the dicarboxylic acid component is 100 mole % and the total mole % of the glycol component is 100 mole %. The invention further relates to a process for preparing the above-identified copolyester. The invention further relates to a blend having from about 5 to 95 wt % of the above-identified copolyester; and from 5 to 95 wt % of a component comprising a flame retardant, a filler, a reinforcing agent, a polymer or a mixture thereof. The invention further relates to an article prepared from the above-identified copolyester and blend.
