“…Also, the polymerization of propargyl bromide and chloride was carried out by the catalyst systems such as PdCl 2 , γ-rays, NiI 2 (Ph 3 P) 2 , W(CO) 6 −CCl 4 − h ν , MoCl 5 , and MoCl 5 −polymer . However, these catalysts generally give only insoluble and intractable polymers.…”

A new class of multifunctional polymers based on poly(l,6heptadiyne) derivatives with various functional groups such as carbazole unit for photoconductive polymers and nonlinear optical (NLO) chromophores for NLO polymers were synthesized by metathesis polymerization. The polymerizations were carried out with MoCI,-and WCI,-based catalysts. The catalytic activity of MoCI, was found to be greater than that of WCI , . The resulting polymers exhibited photoconductivity and large optical nonlinearity. These conjugated polymers have good solubility in common organic solvents, long-term stability toward air oxidation, and high electrical conductivity.

“…Nickel salts are well-known to cyclotrimerize, cyclotetramerize, and to polymerize acetylene, producing benzene, cyclooctatetraene, and amorphous presumably low molecular weight poly(acetylene). − Recently, there have been several reports of the polymerization of acetylene derivatives using late-transition-metal catalysts based on rhodium, − palladium, and nickel. − Late-transition-metal catalysts are particularly attractive as they tend to exhibit greater functional group tolerance than the more electron-deficient early-transition-metal catalysts. To our knowledge, these catalysts have not been applied to the synthesis of poly(cyanoacetylene).…”

Preparation of Poly(cyanoacetylene) Using Late-Transition-Metal Catalysts

et al. 1999

Poly(cyanoacetylene) has been prepared by polymerization of cyanoacetylene using a variety of late-transition-metal (Pd- and Ni-based) catalysts. The effect of reaction conditions on molecular weight and polymer yield was explored. Significant catalyst residues remain in the polymer samples. However, spectra are consistent with the proposed poly(cyanoacetylene) structure. Notable differences in molecular weight, effective conjugation length, and ability to undergo thermal cyclization to a supposed aromatic ladder polymer were observed between these polymers and those prepared using conventional anionic or radical initiators.
