Abstract
Abstract This invention relates to novel, sulfonated terpolymers and the uses thereof. The novel, sulfonated terpolymers of the instant invention preferably have a molecular weight from 5,000 to 250,000, and are prepared by the sulfonation of a polymer obtained by the polymerization of an isoolefin, a conjugated diene, and a cyclic diolefin. The sulfonation reaction may be carried out by use of a complex of a Lewis base with a sulfur trioxide donor. The low molecular weight sulfonated polymers of the instant invention may be neutralized by reaction with inorganic or organic bases. The neutralized low molecular weight polymers of the instant invention, i.e. a molecular weight range of from 5,000 to 45,000, when combined with a plasticizer which interacts with the sulfonate group, e.g. an alcohol, show useful properties as coatings and mastics.
