Abstract: This invention describes the preparation and characterization of cross-linkable fluoropolymers, These cross-linkable fluoropolymers contain keto functional monomer. The keto functional monomer is incorporated on fluoropolymer while crosslinking agent was post-added after polymerization. The cross-linking reaction occurs after water/solvent evaporation or during melt processing.

Abstract: The invention relates to heat treatment of polymorphic semicrystalline or crystallizable polymers to increase the content of the highest melting crystalline form. Such heat treatment results in a polymer powder that has a consistent, uniform melting range, improved flow and improved durability of the powder particle size for applications that require powder flow at elevated temperatures. In addition to improved powder properties, the articles produced from the powders also exhibit better physical properties in both appearance and in mechanical properties. Thus the invention also includes polymer powders and articles produced by the described processes.

Abstract: A composition including a polymeric binder for the negative electrode of a secondary energy storage device is provided. The polymeric binder provides a matrix for particulate electrode-forming materials, which may include an active material and a conductive material. The polymeric binder contains acid functional groups. The polymeric binder also contains other functional monomers, which also may contribute to the performance of the polymeric binder in the negative electrode.

Abstract: Shell-and-tube devices typically require regular maintenance. Described herein is an automated method for tracking the status of individual tubes during maintenance activities and recording status data for review and analysis. Status data may optionally be reported in real-time summary format and/or used to predict time-to-completion. The method helps to reduce the expense of performing maintenance activities in shell-and-tube devices, including shell-and-tube reactors and heat exchangers.

Abstract: The invention relates to the use of a compatible thermoplastic material (film, sheet, or raft) as the base sheet or layer for 3-D printing an article. The use of the base film provides a means of printing a large article, and of reducing warpage by printing directly on the film. The printed article adheres to the film better than to traditional printer surfaces (glass, metal, glue, or reusable films), because the printed article and film weld together by forming chain entanglements, due to being compatible, miscible, or semi-miscible in the melt.

Abstract: This process for synthesizing thiopolymers involves feeding elemental sulfur or sulfides and unsaturated hydrocarbons into an extruder. The extruder is comprised of a screw and a barrel. The screw is rotated so as to pressurize, heat and mix the sulfur or sulfides and unsaturated hydrocarbon to induce inverse vulcanization thereby producing thiopolymers such as polymeric polysulfides. The invented process can be accomplished by using sulfur which becomes molten at the conditions in the extruder or is preheated and unsaturated hydrocarbons as the starting material. The materials are fed through one or more extruders so as to induce mixing and reaction of the materials forming polysulfides.
