Right!

A photodegradable photosensitive polymer refers to a polymer capable of completing a photodegradation process of a polymer.

The photodegradable photosensitive polymer 13hntodeoomp} sin} phatnscnsiti} epnlyrncr polymer quickly initiates chain scission reaction after absorbing light energy. The molecular weight and mechanical strength of the polymer decrease and the solubility increases. This process is called the photodecomposition process of the polymer. The polymer capable of completing the above process is a photodegradable polymer. These resins generally contain diazo, diazonium or azide groups, or compounds containing the above-mentioned groups in the resin. The formation of photo-decomposed radicals with photosensitive groups capable of absorbing ultraviolet and visible light and photo-initiated free radicals. Photodecomposition type photosensitive polymer is an important positive photoresist, and is an excellent photosensitive material for lithographic plate-making. For conventional polymer materials, the presence of a photodecomposition process is not good for anti-aging of polymer materials, but it is beneficial for the preparation of plastic products with an expected life and preventing environmental white pollution.
