摘要：

Various mechanisms are proposed to explain the formation of the photooxidation products of the PE-LD films (ketones, carboxylic acids, vinyl groups). The kinetics of roduct formation are discussed in detail. The experimental results can be explained on the assumption that the rate of ketone formation increases linearly with exposure time. Possible explanations are proposed.
