Abstract: A modified acid neutralizing polymer material includes a substrate having a surface including an acid neutralizing polymer material and a modified layer formed on the acid neutralizing polymer material surface. The modified layer includes a reaction product between a basic salt solution and the acid neutralizing polymer material surface. A method for preparing the modified acid neutralizing polymer material includes receiving a substrate comprising an acid neutralizing polymer material, applying a basic salt solution to the substrate to create a modified substrate through a reaction product between the basic salt solution and the acid neutralizing polymer material to form the modified acid neutralizing polymer material, allowing the basic salt solution to evaporate from the modified substrate, and optionally, removing unreacted basic salt material from the modified acid neutralizing polymer material.

Abstract: A method of making an acid neutralizing polymer includes: a) preparing a first reaction mixture by blending of a polyamide material, a solid strongly basic material, and a halogenated-dimethylalkylamine; b) adding the first reaction mixture to a first compounding machine; c) reacting the first reaction mixture for a time and at a temperature sufficient to produce a first reaction product; d) preparing a second reaction mixture including the polyamide material; e) adding the second reaction mixture to a second compounding machine; f) reacting the second reaction mixture for a time and at a temperature sufficient to produce a second reaction product; g) preparing a third reaction mixture by blending the first reaction mixture and the second reaction mixture; h) adding the third reaction mixture to a third compounding machine; and i) reacting the third reaction mixture for a time and at a temperature sufficient to produce the acid neutralizing polymer.

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.

Abstract: A method of preparing an acid neutralizing polymer powder (ANPP) includes preparing a first reaction product by contacting and reacting virgin polyamide powder material with tert-butoxide in a first aliquot of a polar aprotic solvent and preparing a mixture of an halogenated dialkylalkylamine to a second aliquot of the polar aprotic solvent. ANPP is prepared by mixing the first reaction product and the mixture for a period of time and at a temperature sufficient to produce the ANPP.
