ABSTRACT:
High molecular weight polymer that can form a viscous aqueous solution is chemically modified by mixing the previously formed polymer (as a powder, reverse phase dispersion or oil-in-water emulsion) with water and the reagent for effecting the chemical modification so as to form a viscous aqueous mixture having a viscosity of at least 1OOO cps (Brookfield RVT) and then feeding this mixture as intermittent batches into one end of a tower through which it moves with substantially plug flow and from which it is withdrawn, at the end of the reaction, as intermittent batches. The apparatus for this purpose is also novel.
