Synthesis and solubility of poly(N-methylbenzimidazole) and poly(N-ethylbenzimidazole): control of degree of alkylation

In this paper, synthesis of poly(N‐methylbenzimidazole) (PNMBI) and poly(N‐ethylbenzimidazole) (PNEBI) with various alkylation degrees was achieved by adding enough LiH and controlling the amount of substituting reactant. The degree of substituted methyl or ethyl was determined by elemental analysis...
