The rate of the reaction decreases with increasing number of substituents in the acetylenic halide, and it is higher with acetylenic bromides than with the corresponding chlorides. Methyl magnesium iodide gives equal amounts of 1,1- and 1,3--substitution products, whereas tert.-butylmagnesium bromide does not react. However, for some tert.-butyl substituted allenes there exists an attractive com-...

The molecular weights obtained are very high with extremely broad molecular weight distributions. Poly(tert-butyl-acetylene) (P21) and poly(methyl-trimethylsilyl-acetylene) (P22) are white amorphous polymers, which can easily be solution cast into tough, completely colorless, transparent films. Therefore, the synthetic procedure was...
