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.
