-i- OIL SOLUBLE LOW TEMPERATURE CURING QUATERNARY AMMONIUM MONOMERS ABSTRACT The quaternary ammonium monomers of this invention have the formula Image (I) wherein R is an ethylenically unsaturated organic group R1 is a linear C1 to C4 alkyl group, optionally hydroxy substituted ; X is chlorine, bromine or iodine ; and Y ? is a surfactant anion. The epoxides derivable from the halohydrin of Formula (I) are other monomers of this invention. -ii- 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. The monomers are particularly efficiently incorporated into co- polymers.
