Abstract: The present disclosure relates to polyamide compositions and resulting injection-molded articles that can be plated, e.g., metal coated, to form aesthetic injection-molded articles. The polyamide compositions may include from 45 wt. % to 75 wt. % of an polyamide, from 2 wt. % to 40 wt. % of an etchable filler, from 10 wt. % to 40 wt. % of a semi-structural mineral, and optionally from 0.1 wt. % to 13 wt. % of additive. The polyamide composition imparts very good surface appearance to injection-molded articles that are substantially free of visual defects.

Abstract: A polymer, applications thereof, and method of making a nanofiber nonwoven product is disclosed which includes: providing a spinnable polyamide polymer composition comprising a solution of a polyamide in a suitable solvent, wherein the polyamide has a Relative Viscosity of from 30-300; a basis weight greater than 1 gm/m2, solution-spinning the polyamide polymer composition into a plurality of nanofibers having an average fiber diameter of less than 1 micron (1000 nanometers); and forming the nanofibers into said nonwoven product which thereby has an average nanofiber diameter of less than 1 micron (1000 nanometers). Preferably, the nonwoven product is solution-spun from a process selected from (i) centrifugal spinning using a rotating spinneret or (ii) 2-phase propellant-gas spinning including extruding the polyamide polymer composition in liquid form with pressurized gas through a fiber-forming channel. Suitable solvents include formic acid, sulfuric acid, trifluoroacetic acid, hexafluoroisopropanol (HFIP) and phenols including m-cresol.

Abstract: A method for tuning characteristics of a polyamide nanofiber nonwoven comprising the step of targeting a specific average nanofiber diameter and/or a specific relative viscosity for the polyamide nanofiber nonwoven. The specific average nanofiber diameter is within a range from 100 nm to 1000 nm and/or the specific relative viscosity is within a range from 5 to 75, e.g., from 15 to 50. The process further comprises the steps of extruding a polyamide composition having a moisture content with a pressurized gas through a fiber forming channel having a channel temperature to form the polyamide nanofiber nonwoven having the target average nanofiber diameter and/or relative viscosity and controlling the moisture content, the pressure of pressurized gas, and/or the channel temperature based on the specific average nanofiber diameter and/or the specific relative viscosity.

Abstract: Provided herein are processes for purifying TCH in a feed stream, such as an adiponitrile process stream. The processes include a first separating step of separating the adiponitrile process stream to form a first overhead stream comprising low-boiling components and high-boiling components and a first bottoms stream comprising high-boiling components. The processes also include a second separating step of separating the first overhead stream in one or more distillation columns to form a lights stream comprising low-boiling components, a heavies stream comprising high-boiling components, and a TCH stream.
