Abstract
Soluble polymers of linear and branched structure have been prepared by non-equilibrium, low temperature polycondensation of aromatic tetramines with m-carboranedicarboxylic acid chloride, the products have been characterized and some correlations involved in their formation are studied. It is shown that polycondensation of this acid chloride with tetramines in solution in tetrahydrofuran in the presence of pyridine produces branched polymers, but in N-methylpyrrolidone polyaminoamides of linear or branched structure are formed, depending on the reaction conditions.
