  • Publication number: 20240182659
    Abstract: A method of making an acid neutralizing polymer material includes preparing a first reaction mixture including a buffering agent and an amine salt of either a halogenated tertiary amine or a haloalkyl heterocyclic aromatic amine. The first reaction mixture is added to a first compounding machine and reacted for a time and at a temperature sufficient to produce a neutralized amine. A second reaction mixture including a polyamide material and a strong base is prepared, added to the first reaction product and reacted for a time and at a temperature sufficient to produce the acid neutralizing polymer material. Alternatively, the buffering agent, amine salt of either a halogenated tertiary amine or a haloalkyl heterocyclic aromatic amine, and the polyamide material may be added and reacted for a time and at a temperature sufficient to produce the acid neutralizing polymer material.
