摘要
Disclosed herein are polymer compositions useful in high temperature enhanced oil recovery applications. The polymer compositions include at least 20 mol % of an N,N-dialkyl-N,N-diallylammonium salt and further have a net negative charge. The polymer compositions provide polymer dispersions in water or brine having stable viscosity when maintained at temperatures of 100° C. and above for at least 2 days.
