| titleOfInvention |
Process for preparing an aqueous dispersion of a quaternary ammonium salt containing vinyl copolymer |
| abstract |
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. |
