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.
