Abstract: | Summary Two methods of the synthesis of tributyl ammonium derivatives of glycidyl methacrylate — ethylene dimethacrylate copolymers with various contents of the crosslinking agent were examined. While the two-step process which consists in a reaction with dibutyl amine followed by alkylation with butyl bromide gives products with up to 1.5 mmol/g of required groups, in the case of the single-step reaction of the epoxide group with tributyl amine the content does not exceed 0.4 mmol/g. The use of diamines for increasing the distance between the quaternary group and the polymer backbone does not yield a readily definable product, and cannor therefore become the method of choice. |
