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.

Abstract: A polyamide composition comprising from 45 wt % to 95 wt % of polyamide polymer and from 5 wt % to 55 wt % of a modifier comprising a C18-44 dimer acid or a C18-44 dimer amine or a combination thereof. A number average molecular weight of the polyamide polymer is less than 30,000 g/mol. The polyamide composition has a chemical resistance, as measured by exposure to HCl (10%) for 14 days at 58° C., resulting in a weight loss of less than 3.0 wt %; and a moisture uptake of less than about 2.0 wt % moisture at 95% RH. A process for preparing the polyamide composition is also disclosed.

Abstract: A polyamide composition comprising a base polyamide and an elastomer concentrate comprising: 20-80 wt % of an elastomeric aliphatic polyether having a molecular weight ranging from 400-4000 g/mol; and 80-20 wt % of a concentrate polyamide. The polyamide composition has particular uses as a cable tie and demonstrates improved cold-temperature applications while maintaining high strength, good flammability rating, and excellent processability.

Abstract: A method of producing a polyamide elastomer comprising feeding a salt solution having a solids content of greater than or equal to 80% to a reactor having a phosphorous containing catalyst having a phosphorous level from 5 to 1000 part by million based on the total weight of the catalyst, feeding a polyether amine to the reactor, and reducing the pressure in the reactor once a target temperature is reached to polymerize the salt solution and the polyether amine to form the polyamide elastomer. The polyamide elastomer has particular uses as a cable tie and demonstrates improved cold-temperature applications while maintaining high strength, good flammability rating, and excellent processability.
