Cationic photopolymerization of cyclohexene oxide

Diethoxy‐azobis(pyridinium) Salt as Photoinitiator for Cationic Polymerization: Towards Wavelength Tunability by Cis–Trans Isomerization

“…[2][3][4] Obviously, the growth of such an industry is dependent on the development of new photoinitiators to fulfill requirements for specific applications. Iodonium salts, [5][6][7] aromatic sulfonium, [8][9][10][11][12][13] phosphonium, [14][15][16] and pyridinium salts, [17] and ferrocenium salts [18,19] are typical photoinitiators used for the initiation of cationic polymerization in various applications. The extent of the spectroscopic sensitivity to higher wavelengths is the major concern for the design and use of an efficient photoinitiator for specific applications.…”

Cure behavior of diglycidylether of bisphenol A/trimethylolpropane triglycidylether epoxy blends initiated by thermal latent catalyst

“…In recent years, cationic polymerization of epoxide has been studied intensively. 8,9 In the cationic mechanism, the epoxy groups are opened by active hydrogen that is replaceable by a metal to produce a new physico-chemical bond or a hydroxyl group. Cationic catalyst is generally used as a complex, such as BF 3 -ether, BF 3 -amine, or SbF 6 -epoxide.…”

A Study on the Preparation of the Eco-friendly Carbon Fibers-Reinforced Composites

“…However, they have some problems, such as the toxicity of amine, combined with low heat resistance and the deterioration of mechanical properties at high temperature or at high humidity, which requires energy consumption, resulting in a long curing process [1]. Therefore, catalytic curing agents of epoxy matrix resins have been studied as substitutes for the amine or anhydride agents [2,3].…”
