Rhodium(I) tris(pyrazolyl)borate complexes TpR2Rh(cod) (R = Me, Ph, i-Pr) were found to serve as efficient catalysts for highly stereoregular polymerization of phenylacetylene derivatives (p-YC6H4C⋮CH; Y = H, Me, Cl, CN, CO2Me, COMe, NO2) to give poly(phenylacetylene) species having a head-to-tail, cis-transoidal structure. The catalytic activity was strongly affected by the substituents (R) at the 3- and 5-positions of the pyrazolyl groups, and the more sterically demanding R groups led to higher catalytic activity.

“…Other approaches to a processable polyimide with improved solvent resistance and thermal properties used an internal acetylenic unit as a crosslinking site 3. Studies on many other acetylene‐terminated resins have been reported,4–13 because oligomers and polymers containing acetylenic groups can be polymerized into three‐dimensional void‐free networks under moderate conditions, and the polymers show solvent resistance, moisture resistance, and excellent thermo‐oxidative stability 14…”

Dynamic mechanical analysis is performed on polybenzoxazines from acetylene-terminated benzoxazine monomers, and glass transition temperatures of these polybenzoxazines are found in the range of 329 -368°C. It has been identified that the high glass transition temperature and high thermal stability are due to polymerization of the acetylene terminal group, in addition to oxazine ring polymerization through a comparison study with analogous polybenzoxazines that are obtained from monomers without an acetylene functional group.
