Studies have been made on the conductivities of poly(methyl vinyl ketone‐ co ‐acryl amide) [poly(MVK‐ co ‐AAm)]s after having reacted with phosphorus oxychloride. It was found that the conductivities were dependent on the mol ratio of [AAm] to [MVK], copolymerization temperature, and time. The effect of treatment conditions of POCl 3 on the conductivities of the poly(MVK‐ co ‐AAm)s was shown to be significant. It was observed that the conductivities of the poly(MVK‐ co ‐AAm)s, treated with POCl 3 , are of the order of 10 −6 –10 −9 Scm −1 . The maximum conductivity of the POCl 3 ‐treated poly(MVK‐ co ‐AAm) was obtained as 8.7 X 10 −6 Scm −1 when the mol ratio of AAm to MVK was 0.5. The conductivity of the poly(MVK‐ co ‐AAm) was increased with the treatment time and concentrations of POCl 3 . © 1992 John Wiley & Sons, Inc.
