A method of making an ion triggerable cationic polymer by solution copolymerizing one or more vinyl-functional cationic monomers, one or more water insoluble or hydrophobic vinyl monomers with alkyl side chains up to 4 carbons long, and, optionally, a minor amount of one or more vinyl monomers with linear or branched alkyl groups longer than 4 carbons, alkyl hydroxy, polyoxyalkylene, or other functional groups. The solution polymerization is accomplished by free radical polymerization in a mixture of an organic solvent such as acetone and water. After polymerization is complete, the organic solvent is preferably removed by a continuous process. The continuous process is preferably performed using a plate evaporator system.

The present invention is directed to ion triggerable, water-dispersible cationic polymers. The present invention is also directed to a method of making ion triggerable, water-dispersible cationic polymers and their applicability as binder compositions. The present invention is further directed to fiber-containing fabrics and webs comprising ion triggerable, water-dispersible binder compositions and their applicability in water-dispersible personal care products, such as wet wipes.
