The reaction product of α,ω-diglycidyl ether of oligooxyethylene glycol (MM 1000) with 2-aminopyridine or 2-amino-3-methylpyridine was used as the initial basic oligomer of linear structure. An oligomeric silsesquioxane containing tertiary amino groups in combination with hydroxyl groups in the organic frame of the silsesquioxane core was used as the branched oligomer. Reactive protic cationic OILs were synthesized by complete or partial neutralization of the basic centers of the proposed basic oligomers with ethane and p-toluenesulfonic acids.
