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.
Claims10
A method of preparing an acid neutralizing polyamide powder (ANPP), comprising:
- a) 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;
- 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, where R is an alkyl containing 1-3 carbon atoms, R′ is an alkyl containing 1-12 carbon atoms and X is either chlorine or bromine;
- 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.
