摘要： A method of forming tungsten ingots having improved uniformity of density and improved uniformity in distribution of dopant within the ingot is disclosed. Doped tungsten powder is disposed in a cylindrical mold having sealing means at both ends. The powder completely fills a void space within the mold between the sealing means so that there is substantially no settling of the powder. A pressure of about 560 kg/cm.sup.2 is applied uniformly to the outer surface of the mold to form a cylindrical compact. The compact is removed from the mold and resistance sintered to a density of at least about 85 percent of theoretical density to form the ingot.

摘要： A method and apparatus for filling generally cylindrical molds with powder particles is disclosed. A stream of powder particles is fed into a mold, and the powder particles are compacted in spirally formed layers so that the particles are compacted continuously in localized adjacent areas. The powder filling apparatus is comprised of a blade means configured to direct powder particles to spread evenly in the mold and urge the powder particles to compact while the blade means is rotated about an axis. A shaft is attached to the blade means for rotation of the blade means about the axis. A chuck means is slideably mounted on the shaft means through an axial channel, the chuck means being configured for applying force to the shaft while permitting movement of the shaft axially through the channel. A drive means is operatively connected to the chuck means for applying force to rotate the chuck about the axis. The powder particles are filled to a high and uniform fill density by the powder filling method and apparatus of this invention.

摘要： A fluorochemical additive is the reaction product under polymerization conditions of monomers that include: (a) an aromatic polycarboxylic acid as an anhydride, ester, or ester chloride; (b) at least one fluorinated reactant; and (c) at least one aliphatic amine, mercaptan, or alcohol. Optionally, a crosslinking agent can be used. The components of the additive all can be viewed as contributing to the performance of the disclosed additive. The fluorine-containing component is generally insoluble in molten polymers and will tend to migrate to the cooled surface thereof where the fluorinated moieties provide repellency characteristics when used in adequate quantities, generally at least about 30 wt % depending on the fluorinated reactant used to make the additive. The aromatic component appears to facilitate solubility and speed up the orientation process of the additive within the molten polymer. The aliphatic component to the reaction mixture appears to assist in anchoring the reaction product additive in the bulk polymer structure. Together, the components form a fluorinated reaction product additive that can be added to a molten polymer for integration into the resulting product to impart improved resistance to oil, water, and alcohol.
摘要翻译：氟化合物添加剂是在单体的聚合条件下的反应产物，其包括：（a）作为酸酐，酯或酯氯化物的芳族多元羧酸; （b）至少一种氟化反应物; 和（c）至少一种脂族胺，硫醇或醇。任选地，可以使用交联剂。添加剂的组分都可以被认为有助于所公开的添加剂的性能。含氟组分通常不溶于熔融聚合物，并且倾向于迁移到其冷却的表面，其中氟化部分当以足够量使用时提供排斥特性，通常至少约30重量％，这取决于用于制备添加剂。芳族成分似乎促进溶解性并加速了熔融聚合物内添加剂的取向过程。反应混合物中的脂族组分似乎有助于将反应产物添加剂锚定在本体聚合物结构中。这些组分一起形成氟化反应产物添加剂，其可以加入到熔融聚合物中以整合到所得产物中以改善对油，水和醇的耐受性。

摘要： The present invention discloses a vapor phase method of introducing a branching agent such as THPE into a solid polycarbonate while simultaneously crystallizing the solid polycarbonate. The partially crystalline polycarbonate containing a branching agent introduced in this manner is suitable for use in the preparation of branched polycarbonates by solid state polymerization. Branching in the polycarbonates so produced is demonstrated by rheometric measurements. Such branched polycarbonates are known to possess increased material melt strength, shear sensitivity, and complex viscosity ratio, and are particularly well-suited in blow molding applications.
