Claim 9:
10. An acid neutralizing polyamide powder (ANPP) produced according to a method comprising:
a) preparing a first reaction product by contacting and reacting a virgin polyamide powder material with tert-butoxide in a first aliquot of a polar aprotic solvent;
b) preparing a mixture of a halogenated dialkylalkylamine having a general chemical formula of R2N—R′—X and a second aliquot of the polar aprotic solvent, wherein R is an alkyl containing 1-3 carbon atoms, wherein R′ is an alkyl containing 1-12 carbon atoms, wherein X is either chlorine or bromine, and wherein R is not the same as R′; and
c) preparing the ANPP by mixing the first reaction product and the mixture,
wherein each of steps a) and c) is for a respective period of time and at a respective temperature sufficient to produce the first reaction product and the ANPP.
