What Is Photo Polymerisation

Photopolymerization is a technique that uses light (visible or ultraviolet; UV) to initiate and propagate a polymerization reaction to form a linear or crosslinked polymer structure. From: Journal of Controlled Release, 2016.

Why is photopolymerization important?

Photopolymerization is an important area of investigation due to its wide industrial applications and huge potential in simple and fast production of materials with special properties.

What do photoinitiators do?

A photoinitiator is a molecule that creates reactive species (free radicals, cations or anions) when exposed to radiation (UV or visible). … Some small molecules in the atmosphere can also act as photoinitiators by decomposing to give free radicals (in photochemical smog).
