Basics about photopolymerization

Polymers are giant molecules or macromolecules built up by the linking together of large numbers of much smaller molecules. These small molecules that combine with each other to form polymer molecules are termed monomers, and the reactions resulting in polymer formation is referred to as polymerization. There may be hundreds, thousands, tens of thousands, or more monomer molecules in a single polymer molecule having a high molar mass. Because these molar masses may be not all similar, they exhibit a specific distribution, either narrow if chains have similar lengths or broad in the opposite case.
