Polymerization of cis-5,6-bis(trimethylsiloxy)-1,3-cyclohexadiene and other substituted cyclohexadienes |
摘要 |
The monomer cis-5,6-bis(trimethylsiloxy)-1,3-cyclohexadiene can be polymerized with certain nickel II catalysts, such as bis[(ally)trifluoroacetatonickel(II)], bis[(allyl)pentafluorophenoxynickel(II)], and bis[(allyl)iodonickel(II)]. The resulting polymer is a precursor to poly(para-phenylene). Other substituted cyclohexadienes may also be polymerized by these catalysts to form useful polymers.
