Mechanism of gas formation in catalytic decomposition of polypropylene

The catalytic decomposition of polypropylene was studied. The production of gas precursors was found essential to decomposition. Attempts were made to elucidate the gas formation mechanism. The most important elementary reaction is the intramolecular rearrangement of chain-end secondary carbonium ions in the liquid fraction to inner tertiary carbon atoms; the C9 fraction was produced by β-scission of the rearranged ions. The C4 and C5 fractions were subsequently obtained by the decomposition of the C9 fraction.
