PROCESS FOR PREPARING POLYAMIDOAMINE-EPICHLOROHYDRIN CONTAINING 1,3-DICHLOROPROPAN-2-OL LEVELS UNDETECTABLE BY VAPOR PHASE CHROMATOGRAPHY CONVENTIONAL MEANS

摘要

the invention is a process for the manufacture ofpolyamidoamine epichlorhydrin resin content.dichloro - 1, 3 - 2-propanol and theordinary gas chromatograph. this processis to make the products resulting from thecondensation, constructed and epichlorohydrinin the two columns of activated carbon. wethus obtained aqueous resins without toxic chemicals.especially appreciated as resistance additivesin the manufacture of wet paper medical use.cosmetic or food.
