Abstract:
A multi-directionally flowing horizontal continuous process for aqueous free radical polymerization of water-soluble monomers to form a water-soluble polymer comprising the steps of:a) continuously feeding an aqueous solution of one or more water-soluble monomers having a concentration of from about 5 to about 80 percent by weight to a horizontally-aligned reactor having an interior cavity, an exterior housing, an inlet end, an outlet end and a conveying and mixing device within said interior cavity;b) mixing and backmixing said solution as it is conveyed from said inlet end to said outlet end through said interior cavity of said reactor by said device under free radical polymerization conditions; and,c) continuously withdrawing the water-soluble polymer from said outlet end of said reactor.
