polymerization degrees are obtained instead; thei r chemical structure is presented in Figure 2 (c) where n is typically 0.2. DGEBA oligomers typically contain a certain amount of hydroxyl groups, that play an important catalytic role in the kinetics of the curing process, providing a higher viscosity which is dependent on n.

The action and e ciency depend on many factors such as polyelectrolyte charge [28], the nature of its charged groups [29], the hydrophobicity of the polymer [30], degree of polymerization [21] and other factors [31,32].

Photocatalysts in Polymerization Reactions

double bonds of vinyl monomers and initiate the radical polymerization. Cationic polymerizations are usually preceded by photolysis of onium compounds (iodonium, sulfonium, pyridinium, diazonium, pyrylium, etc) and the resulting cationic species or strong acids initiate a ring opening polymerization on epoxides[13] or oxetanes[14] or react on
