Polymer additives prepared using base addition and related methods

摘要

Problem to be solved: to provide a method for evaluating the polymer additive content a in the polymer particle mixture.A method for evaluating the polymer additive content a in a polymer particle mixture isDetermining the concentration B of the metal cation in a polymer particle mixture comprising a parent polymer particle and a polymer additive particle;Metal cationsSelected from alkaline earth metals and alkali metals other than sodium (NA).Metal cationsWater soluble base can be formedAndDetermining the concentration C of the metal cation in the parent polymer particle andDetermining the concentration D of the metal cation in the polymer additive particle andA method comprising calculating a polymer additive content a using formula a = (B-C) / d.No selection
