Some sulfur containing polyesters having properties of synergistic AO were described, like a product formed from 2-(2-hydroxyethylthio)-l-methyl-4-[2-(2-hydroxyethylthio)-l-methylethyl]cyclohexane and dimethyl 3,3 -thiodipropionate [183] (141), an esterification product of 3-n-dodecylthiopropionic add with poly(ethylene ycol) [184] (142) or a polycondensate of sebacoyl chloride with 4,4 -dimercaptodiphenyl sulfide [185].

A series of high molecular weight poly(thioether ketone)s (M = 55,000-100,000), eg, (24) and (25), have successfully been prepared from bis(4-mercaptophenyl) ether (4,4 -dimercaptodiphenyl ether) or bis(4-mercaptophenyl) sulfide (4,4 -dimercaptodiphenyl sulfide) by reaction with a series of ketone-activated aromatic fluoro-compoimds in the presence of anhydrous K2CO3. The polymers are amorphous and soluble in common organic solvents. They show TgS from 154 to 251°C and excellent thermal stability [temperatures of 5% weight loss (Tds) even above 500°C] (65).
