Continuation of the process reduces the polymer to small fragments that include benzaldehyde and
methyl phenyl ketone [

When solid polystyrene is subjected to an
, carbonyl, peroxide, and carboxylic acid
groups form on the surface of the polymer [
528
]. The reaction rate is proportional to the concentration
of the ozone and the surface of the sample. As a result of the ozone action, intramolecular cross-
linking takes place. The reaction mechanism of the ozone attack on polystyrene can be shown as
follows [
