The Polymer Chemistry of Butatrienes and Their Potential as Precursors of Novel Polyacetylenes
Abstract
In this work, we explore novel approaches to new polymers the poly(butyne-l,4-diyl). These are synthsized from 1,2,3-butatrienes, highly unsaturated monomers. Tetrasubstituted systems bearing bulky aliphatic substitutents can be polymerized under controlled conditions. The tetramethyl system cannot be controlled. Using diphenyl substitutents, we have developed a new approach to the synthesis of soluble polyacetyelenes. Using 1,4-diphenylsubstituted butatrienes, we polymerize these monomers to form a non-conjugated poly(l,4-diphenyl-2- butyne-l,4-diyl) . This soluble, processable materials can be converted to the conjugated (poly(diphenylacetyelen-ait-acetylene) for through the application of strong protic bases. we provide synthesic procedures and characterization of both the precursor and final polymers.
