## 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

Acetylene and vinylacetylene mixtures were pyrolyzed at 400-500Β°C in the absence and presence of O2 or NO. The major product of the interaction between CzH2 and C4H4 is polymer, but benzene is also produced. Both the C2H2 removal and CsHs formation rates are first-order in C2Hz and C4H4. The rate co
The pyrolysis of acetylene-etyrene mixtures has been studied from 450-550Β°C in a quartz reaction vessel in the absence and presence of 0, or NO. The rates of disappearance of reactants and formation of adducts are first-order in each reactant. The major product is polymer, with the adducts accountin
