Abstract: A method for enhancing solid state polymerization of polyethylene terephthalate is disclosed in which at least one monomeric unit of diacid and/or dimethyl ester comprising at least one pendant chemical side group is copolymerized with a diol and a diacid or a dimethyl ester. The at least one pendant chemical side group may include groups chosen from tertiary butyl, hexyl, pentyl, butyl, propyl, ethyl, methyl, nitrosyl (NO2) and sulfonyl (SO2) groups.

Abstract: The present invention relates to a process for making a lower molecular weight polymer from a solid stated higher molecular weight feed stock chip. In particular, the molecular weight of an industrial resin or a bottle resin is reduced in a controlled manner by the introduction of ethylene glycol. If the industrial resin is to be employed for industrial fibers, the ethylene glycol may be added at the extruder for spinning the industrial fiber. On the other hand, should the high molecular weigh chip be used for bottle resin, the molecular weight may be reduced by the introduction of ethylene glycol at the extruder for injection molding of preforms of a lower molecular weight. The ethylene glycol/polymer ratio is determined by the reduction in molecular weight that is required. The preferred resin is polyester polymer or copolymer, and especially polyethylene terephthalate (PET). The present invention comprises a process for reducing the molecular weight of a solid stated polyester feed stock resin comprising obtaining polyester resin having an IV greater than about 0.8 dl/g; and mixing ethylene glycol with said polyester wherein said ethylene glycol is present in a stoichiometric amount to reduce the IV to the required level.

Abstract: A method of manufacture of a rapid dyeing, deep dyeing, open structure polyamide yarn and to the yarn and to a fabric produced from the yarn includes the step of applying an aqueous finish to substantially all of the rapid dyeing, deep dyeing, open structure polyamide filaments. The aqueous finish consists essentially of a fluorosurfactant dissolved in water that is applied to bulked continuous filament yarn at an effective concentration level of preferably 150 to 600 parts per million by weight of flourine on yarn. The aqueous fluorosurfactant finish is applied at a point after texturizing and before windup.
