Photopolymerization in dispersed media is an interesting alternative to classical synthesis methods for elaborating polymers displaying high molar masses with high reaction rates in an environmentally friendly manner. This chapter presents emulsion radical photopolymerization initially stabilized with self-assembled (macro)molecules and giving ...

Micromolding and photopolymerization
Advanced Materials, 1997Micromolding techniques for the fabrication of polymer microstructures are discussed with reference to the features important for commercial success. Particular emphasis is placed on a recently developed photo‐polymerization reaction injection molding (RIM) technique.

Photopolymerization in Cholesteric Mesophases
Molecular Crystals and Liquid Crystals, 1984Abstract Cholesteric liquid crystalline monomers undergo efficient photopolymerization to “freeze in” the planar texture characteristic of low molar mass cholesteric liquid crystals. The monomers consist of polymerizable moieties separated from the cholesteryl mesogens by flexible spacer groups.

Photopolymerization of carbazolyloxiranes
Polymer International, 1995AbstractPhotopolymerizations of 1‐allyloxy‐3‐(carbazol‐9‐yl)‐2‐propanol glycidyl ether and 1‐(carbazol‐9‐yl)‐4‐oxa‐2‐pentanol glycidyl ether with diaryliodonium salts in solution and in bulk are reported. These reactions give oligomers of degree of polymerization 4–6. The influence of the functional groups of the monomers on the rate of polymerization,

Vat Photopolymerization Processes
2015Photopolymerization processes make use of liquid, radiation-curable resins, or photopolymers, as their primary materials. Most photopolymers react to radiation in the ultraviolet (UV) range of wavelengths, but some visible light systems are used as well. Upon irradiation, these materials undergo a chemical reaction to become solid.

Advances in cationic photopolymerization
Pure and Applied Chemistry, 2012This review discusses cationic UV-curing processes of vinyl ethers, propenyl ethers, and epoxy monomers. Cationic photopolymerization based on photogeneration of acid from onium salts induced by UV light and consecutive polymerization initiated by photogenerated acid was first proposed at the end of the 1970s.

On cyanogen photopolymerization
European Polymer Journal, 1999Abstract Cyanogen photopolymer was prepared by irradiating its solution in polar solvents such as tetrahydrofuran (THF), methanol and ethanol and non polar aliphatic solvent with UV light of a high pressure mercury lamp (main emission: λ >270 nm) and by sunlight irradiation ( λ >300 nm). The resulting photopolymers were black tarry products.
