    摘要： Water soluble polymeric flocculants are prepared by photopolymerizing olefinically unsaturated hydrophilic monomer(s), the medium of photopolymerization being enveloped in a moist, humid gaseous atmosphere. The humidity of the enveloping environment facilitates solubilization of the resultant flocculants, without substantial decrease in the molecular weights thereof, and ensures against the by-production of water insoluble fractions.

    摘要： Water-soluble (meth)acrylic acid/methallylsulfonate copolymers, containing less than 20% by weight of the methallylsulfonate comonomer, are well suited as scale inhibitors for aqueous environments, especially those comprising essentially equal amounts by weight of both acrylic and methacrylic acids.

    摘要： The thin rubbery layer resulting from the photopolymerization of a thin layer of an aqueous solution of acrylic monomer(s) is face surface coated with a coating of an alkali metal sulfite and/or metabisulfite, and is then shredded, dried and ground to provide acrylic polymer/copolymer from which virtually all residual monomer has been depleted and which is well suited for use as a polymeric flocculant.

    摘要： Water soluble polymeric flocculants are prepared by photopolymerizing olefinically unsaturated hydrophilic monomer(s), the photopolymerization recipe including a polyhydroxylated organic additive, such as gluconic acid. Such polyhydroxy compound facilitates solubilization of the resultant flocculants, without substantial decrease in the molecular weight thereof, and ensures against the by-production of water insoluble fractions.

    摘要： Process of preparing anionic polyurethane latexes without the addition of a foreign emulsifying surface active agent comprising rendering the basic polyester or polyether constituent of the latex intrinsically emulsifiable or dispersible in water by incorporating an anionic functional group in the chain thereof and reacting this basic constituent with a diisocyanate in order to obtain a prepolymer which is then emulsified in water.The latexes obtained are advantageously applied in coating and impregnation processes, finishing of leather, and as binders for nonwoven fabrics.

    摘要： Process for preparing acrylic monomers comprising reacting, in aqueos medium, amino alkyl esters of (meth) acrylic acid with a quaternizing agent wherein the aqueous solution obtained is washed with a water-insoluble solvent and the solvent thereafter removed. The quaternized monomers prepared are directly polymerizable to high molecular weight homopolymers or copolymers useful as cationic flocculants.This is a continuation of application Ser. No. 603,173 filed Aug. 8, 1975, now abandoned.
