Abstract: The present invention relates to a composition comprising: a copolyester of polyethylene terephthalate and a dicarboxylic acid or its ester equivalent, and not more than 100 microequivalents per gram of said copolyester of an anhydride selected from the class consisting of succinic, glutaric, benzoic, maleic and phthalic anhydride, said composition having a CEG content greater than about 25 microequivalents per gram and an IV greater than about 0.65. The present invention also concerns a method of making a composition having reduced caustic stress cracking, comprising: reacting terephthalic acid or its ester equivalent and another dicarboxylic acid with ethylene glycol by esterification followed by polycondensation to make a polyethylene terephthalate copolyester; adding at the end of said polycondensation not more than 100 microequivalents per gram based on said copolyester of an anhydride selected from the class consisting of succinic, glutaric, maleic, benzoic, and phthalic anhydride, said composition having a CEG content greater than about 25 microequivalents per gram.

Abstract: A filament comprising a synthetic polymer and characterized by a hexalobal cross-section having three major lobes and three minor lobes, and a major radius (R1) and a minor radius (R2). Each lobal cross-section having essentially straight side portions extending outwardly and tangent to a convex tip at each end. The ratio of the major radius (R1) to the minor radius (R2) defining an exterior modification ratio (R1/R2) of greater than (1).
