摘要： A continuously cast copper ingot is made by a procedure in which turbulence is imparted to the metal/solid interface during the casting operation. The ingot is then hot worked to form a billet having a smaller average grain size and a larger diameter than possible in the past. The billet is especially useful for making electroplating anodes used in the damascene process for making copper interconnects in silicon wafers.

摘要： The invention is a novel method for the late introduction of additives into a process for making condensation polymers. The method employs a reactive carrier that functions as a delivery vehicle for one or more additives. The reactive carrier reacts with the condensation polymers, thereby binding the reactive carrier in the polymer resin and preventing the emergence of the reactive carrier from the polymer resin during subsequent thermal processing.

摘要： Disclosed is a polyethylene glycol modified copolyester fiber that has exceptional moisture management characteristics and that can be formed into exceptionally comfortable fabrics. The copolyester fiber includes polyetylene terephthalate in an amount sufficient for the copolyester fiber to possess dimensional stability properties substantially similar to those of conventional, unmodified polyethylene terephthalate fibers, polyethylene glycol in an amount sufficient for the copolyester fiber to possess wicking properties that are superior to those of conventional, unmodified polyethylene terephthalate fibers, and chain branching agent in an amount less than about 0.0014 mole-equivalent branches per mole of standardized polymer.

摘要： The invention is a method of coloring melt spun condensation polymers while avoiding hydrolytic degradation and maintaining the melt viscosity of the polymer. The method comprises adding a liquid dispersion of a colorant to the melt phase of a condensation polymer, and in which the amount and type of the liquid in the dispersion will not substantially affect the melt viscosity of the condensation polymer; and thereafter spinning the colored melt phase condensation polymer into filament form. In another aspect the invention is a polyester filament comprising polyethylene terephthalate, a colorant, and a nonaqueous organic liquid that is soluble in melt phase polyester, and has a boiling point above 300 DEG C, but that otherwise does not modify the polymer chain.

摘要： An electrical connector (10) made from a Be-Cu alloy can be crimped at room temperature without localized annealing of the crimp section first. Sufficient ductility and tensile strength are imparted to the alloy by cold working the alloy, after final solution annealing, by at least 40 % in terms of area reduction and then overaging the alloy during age hardening.

摘要： A method is disclosed of producing a blended fabric of polyester and cotton with superior low pilling characteristics. The method comprises polymerizing a melt consisting essentially of terephthalic acid, ethylene glycol and at least about 1300 parts per million of pentaerythritol to an intrinsic viscosity of at least about 0.55 dl/g. The resulting polymer can be spun into filament, textured, cut into staple, spun into yarn, and formed into fabric. The method and resulting polyester also have advantages in the production of polyester bottle resin and the resulting bottles.

摘要： A method is disclosed of producing a copolymer of polyethylene terephthalate and polyethylene naphthalate. The method comprises esterifying a combination of a diester of naphthalene, terephthalic acid, and ethylene glycol to produce an esterification reaction mixture that includes the alcohol byproduct of the naphthalene diester, distilling the reaction mixture to remove at least a portion of the esterification byproducts from the reaction mixture in the form of a vapor stream of which the majority component is water vapor and which includes the alcohol byproduct of the naphthalate ester in the vapor state, and combusting at least a portion of the vapor stream under conditions sufficient to decompose at least a portion of the alcohol byproduct present in the vapor stream.
