Process for the polymerization of tri-substituted silylalkynes |
| abstract |
Polymeric trisubstituted silylalkynes useful for forming gas separation membranes are prepared at accelerated polymerization rates and with improved yields in the presence of a Group VB or VIB metal halide catalyst such as TaClâ‚…, by employing about 0.1 to 5 mole %, based upon total alkyne concentration, of a trialkylgermylalkyne compound. |
