Second order rate constants for C2H2 or C2D2 polymerizations into vinylacetylene and higher C,H, products have been measured in a static reactor by dynamic mass spectrometry between"770-980 K. They are nearly identical within experimental error (-+50%). It is shown that these results are consistent
## Abstract The polymerization of acetylene below 550Β° has been examined in a static system. For unpacked vessels it was found possible to obtain reproducible results, from which secondβorder rate constants, and an activation energy of 46Β·7 | 2 kcal., have been obtained. The effect of a large numbe
This comment refers to the recent article of this title by S. W. Benson [ll, in which he returns to an H-atom chain mechanism for the low-temperature acetylene pyrolysis. That article contains a fairly complete chain mechanism and a critique of the alternative molecular (vinylidene) scheme proposed
