The composition can comprise repeat units derived from a first diol such as, for example, 1,3-propanediol and a sulfonated dicarboxylic acid such as, for example, 5-sulfo-isophthalic acid. The dyeable polyester composition can comprise repeat units derived from the copolyether composition, an acid such as, for example, terephthalic acid, and a second diol such as, for example, 1,3-propanediol. Also disclosed is a process that can be used for producing the copolyether composition. The process comprises contacting the first diol with the sulfonated dicarboxylic acid. Further disclosed is a process that can be used for producing the dyeable composition in which the process comprises (1) contacting, in the presence of a catalyst, the copolyether composition with a diol such as, for example, 1,3-propanediol, and a dicarboxylic ester such as, for example, dimethylterephthalate or (2) contacting an acid such as for example, terephthalic acid and a diol such as, for example, 1,3-propanediol to produce an intermediate and thereafter contacting the intermediate with the copolyether.

摘要： The present invention is a method of preparing a high molecular weight copolyester bottle resin that has excellent melt processing characteristics. The method includes the steps of reacting a diacid or diester component and a diol component to form modified polyethylene terephthalate, wherein diol component is present in excess of stoichiometric proportions. Together, the diacid or diester component and the diol component must include at least 7 percent comonomer. The remainder of the diacid component is terephthalic acid or dimethyl terephthalate and the remainder of the diol component is ethylene glycol. The modified polyethylene terephthalate is copolymerized in the melt phase to an intrinsic viscosity of between about 0.25 dl/g and 0.40 dl/g to thereby form a copolyester prepolymer. Thereafter the copolyester prepolymer is polymerized in the solid phase to form a high molecular weight bottle resin that has an intrinsic viscosity of at least about 0.70 dl/g, and a solid phase density of less than 1.413 g/cc.
