Abstract

The methylation of polybenzobisthiazole in dimethylsulfate produces an ndopable polymer which has previously been shown to have high electrical conductivity. The reaction conditions have been shown to chemically degrade the polymer chains, decreasing the molecular weight to about 20% of the original value. A methylationdemethylation scheme has been used to clarify the degree of chain scission.
