Summary
Radical polyaddition of 1,3-dimercaptobenzene onto 1,5-hexadiyne yields sulfur containing polyenolthioethers. By using the method of unstoichiometric ratio not only the molar masses but also the functional end groups of the products can be controlled. The telechelics synthesized are soluble in common solvents such as benzene, toluene and chloroform.
