synopsisAcetic and formic acids and acetone are products of the oxidation of propylene and ethylene polymers and copolymers. The two-and three-carbon products can be accounted for as the result of intramolecular attack by radicals, leading to &oxidation. A high proportion of scissions in polypropylene involves multiple intmmolecular attack.This papcr reports some observations pcrtincnt to the mechanism of oxidation of polyethylene and polypropylene. A number of previous investigations have dealt with other aspects of the oxidation process, including effects of temperature, crystallinit~y, and other external conditions. '-I8

synopsisProducts of the oxidation of cis-polyisoprene boiling lower than water have been resolved and identified. They are: acetaldehyde, methyl formate, propionaldehyde, acetone, methanol, sylvan, methacrolein, ethanol, butanone, and butenone. Possible mechanisms for their origin are discussed.
