摘要: A rhodium-based multicomponent catalytic system for well-controlled living polymerization of phenylacetylenes has been developed. The is composed readily available and bench-stable [Rh(nbd)Cl]2 , aryl boronic acid derivatives, diphenylacetylene, 50 % aqueous KOH, PPh3 . This offers a method the facile versatile synthesis various end-functionalized cis-stereoregular poly(phenylacetylene)s because components from acids diphenylacetylene were introduced to initiating end polymers. reaction shows typical nature with high initiation efficiency, molecular weight resulting can be controlled very narrow molecular-weight distributions (Mw /Mn =1.02-1.09). experimental results suggest that present higher activity than activities other systems previously reported.
