Abstract
-
Seventeen thiazole polymers were prepared by the polycondensahon of α-bis-bromoketones with dithioamides, and the polymers were investigated for preparing heat-resistant fibers and films. Tough, stiff fibers and films were made from four of the polymers; however, each of these polymers melted below 300°C. The other polymers studied did not melt below 500°C, and they had excellent thermal stabilities, but they did not have good fiber-and film-forming properties because of their low molecular weights. All of the polymers prepared had some crystallinity Two of the polymers were soluble in organic solvents; the others were soluble only in strong acids.
