Abstract: The quaternary ammonium monomers of this invention have the formula ##STR1## wherein R is an ethylenically unsaturated organic groupR.sup.1 is a linear C.sub.1 to C.sub.4 alkyl group, optionally hydroxy substitutedX is chlorine, bromine or iodineY.crclbar. is a surfactant anion.The epoxides derivable from the halohydrin of Formula (I) are other monomers of this invention.The monomers are soluble in common organic solvents and comonomers. The invention is also directed to addition polymers of these monomers and to methods of producing both the monomers and the polymers. The halohydrin monomers and the polymers are stable at acid pH values, although capable of reacting with materials reactive with the hydroxyl and/or halide groups. Upon heating, they are self-reactive and can become cross-linked. At alkaline pH values they become self-reactive; the polymers crosslink slowly even at room temperature, with a crosslinking rate increasing rapidly with temperature.

Abstract: An addition polymer is disclosed, the utility being to apply the same as a film to a hydraulic cement-containing article prior to curing, such as concrete, asbestos-cement shingles and the like, for example, to prevent moisture loss during the early hardening period. The polymers are formed of about 10 to 50 percent by weight of an ester of acrylic or methacrylic acid, the alcohol moiety of which has from 12 to about 20 carbon atoms, about 40 to 89.5 percent by weight of a vinyl aromatic monomer, and about 0.5 to 5 percent of a copolymerizable ethylenically unsaturated carboxylic acid, vinyl sulfonic acid, or salts thereof, preferably 15 to 30 percent of the ester, 69 to 84 percent of the vinyl aromatic material, and 1 to 3 percent of the unsaturated acid. In addition to use on concrete, the materials are useful for application to asbestos-cement shingles, prior to curing, and other similar uses.
