ABSTRACT:
A hydrocarbon polymer, such as high density polyethylene, is rendered photodegradable through the introduction into the polymer chain of photosensitive >C= O groups by reacting the polymer with a compound such as NOCl in the heterogeneous phase in an acid environment so that - NO groups are introduced into the polymer chain which are converted into >N--OH groups and then subjecting the resultant polymer to hydrolysis so that the >N--OH groups are converted into photosensitive >C = O groups.
