摘要：

Isobutane and isopentane were selectively obtained by polyethylene catalytic decomposition using the NaY-type zeolite catalyst. Back biting reactions are thus essential to gas formation during the catalytic decomposition of polyethylene. Chain-end secondary carbonium ions cause back biting reactions involving intramolecular rearrnagement to form the C9 fraction. Isobutane and isopentane are then produced by decomposition of the gasification precursor C9 fraction.
