Abstract : The initiator that has most frequently been used to metathesize functionalized olefins---WCl6 + (CH3)4Sn---is an effective initiator for the polymerizations of acetylenes substituted by cyano, ester, and halogen groups. Various initiators effective for acetylenic hydrocarbons fail with these funtionalized derivatives. (Author)
