ABSTRACT:
A resinous polyelectrolyte, especially suitable for use as a tackifier in latex adhesives, comprises an ionizable resinous mixture which is ionized with a volatile ionizing agent, said ionizable resinous mixture being the reaction product of a rosin, a carboxylic acid, and a C.sub.1 -C.sub.18 mono-alcohol, said ionizable resinous mixture having a softening point not substantially above about 125.degree. C. and an acid number of between about 30 and 150, said reaction product comprising the carbocyclic nucleus of rosin having at least one carboxylic acid group and at least one carboxylic acid ester group of said mono-alcohol.
