ABSTRACT:
A process for preparing a polymer having repeating units corresponding to the structure ##STR1## wherein R is ##STR2## y is in the range of 0.005 to 0.10, x is in the range of 0.01 to 0.50 when R is ##STR3## x is in the range of 0.01 to 0.30 when R is ##STR4## and n is at least 200. The polymer is prepared by reacting a diiodoaromatic compound and elemental sulfur.
