Abstract: A sound absorbing multi-layer composite for a vehicle that reduces sounds along an acoustic path is configured with a non-foam polymeric layer and a face layer for dissipating sound energy. Also, the face layer may be made of a nonwoven polymer comprising at least 60% of a polyamide containing an aliphatic diamine having 6 or more carbon atoms and an aliphatic diacid having 6 or more carbon atoms. The weighted overall average fiber diameter of the composite is from 2 microns to 25 microns.

Abstract: The present disclosure relates to polyamide compositions and resulting injection-molded articles that can be plated, e.g., metal coated, to form structurally aesthetic injection-molded articles. The polyamide compositions may include from 40 wt. % to 80 wt. % of a polyamide, from 0.5 wt. % to 40 wt. % of an etchable filler, from 5 wt. % to 30 wt. % of glass fiber, optionally less than 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 and excellent mechanical properties to injection-molded articles that are substantially free of visual defects.

Abstract: Reaction pathways and conditions for the production of nitrogen-containing chelators, such as a glycine derivative, are described herein. In particular, the present disclosure describes a process for the production of a nitrile intermediate at a high yield and/or purity. This process includes reacting a dinitrile compound with an aldehyde and a hydrogen cyanide to form the nitrile intermediate. The nitrile intermediate may then be further processed to produce the chelators at a high yield and/or a high purity.

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 polymer films including a polyamide composition of PA6 and PA66/6. The provided films are particularly useful as packaging materials as they exhibit improved toughness, e.g., puncture and impact resistance, relative to that of conventional films that include only PA6 as a polyamide component. Also provided are methods for making the provided films, and articles that include the provided films.
