Together with 'good' photochemical processes there are some 'bad' as well. This book is about photodestruction and light stabilisation and is devoted to these processes; for example, the heterochain polymers.

Cellulose and its derivatives - cellulose acetate - are renewed polymers. There are many data about the nature of free-radical particles, being formed at irradiation of cellulose by ultraviolet light. This title presents main types of macroradicals, with indication of atom and groups of atoms after removal of which these macroradicals are formed.
