Abstract : A three step procedure for the synthesis of acetylene terminated polymers was studied. The meta- and para- ATB systems, made from Bis Phenol A, were used to develop a process which would be amenable to large scale production. Several changes in the work-up of the reactions were made to reduce the use of carcinogenic solvents and to eliminate costly and unwieldy chromatography columns. The use of toluene as a solvent permitted efficient removal of palladium and copper at significantly lower cost. Products and major by-products in the three steps were characterized by analytical techniques including HPLC and NMR. (Author)
