ABSTRACT:
The present invention relates to a process for the encapsulation of a solid substrate with a neutralized sulfonated polymer, which comprises the steps of: (a) forming a solution of a non-conjugated, diene polymer in a solvent selected from the group consisting of aliphatic, aromatic hydrocarbons and mixtures thereof; (b) contacting the solution of the unsaturated polymer with a sulfonating agent at a sufficient temperature and for a sufficient period of time to form a solution of a sulfonated polymer containing free acid; (c) forming a solution of a base selected from the group consisting of alkali metal hydroxides and mixtures thereof in a mixtrue of an aliphatic alcohol and a hydrocarbon, the hydrocarbon being selected from the group consisting of aliphatic and aromatic hydrocarbons and mixtures thereof; (d) adding the solution of base to the solution of sulfonated polymer in an amount sufficient to neutralize the polymer and the free acid, thereby forming a coating solution; (e) contacting the solid substrate with the coating solution while removing the solvent therefrom, thereby forming an encapsulated substrate. In a preferred embodiment, the solvent removed during step (e) is recovered and distilled to separate the solvent into at least two fractions, a fraction containing substantially hydrocarbon and an alcohol containing fraction. The separated solvents are then recycled to dissolve the polymer in step (a) and to dissolve the base in step (c).
