WebbMonomers or polymers are joined to form longer chains. Polymers are broken down into shorter chains or monomers. An OH group from one component and an H atom from the other form a water molecule. A molecule of water is consumed. Its atoms are added to a bond, putting an OH group on one end and a hydrogen atom on the other. Webb12 apr. 2024 · This shows that during the photopolymerization reaction, the monomers combine to form a polymer structure - double C=C bonds turn into single C-C bonds (Žukauskas et al., 2015; Baldacchini et al., 2024). In addition, the double bonds are reduced when the monomers are washed out. ray\\u0027s tractors
