Photopolymerization of methyl methacrylate - toward high molecular weights for high speed thermoplastics manufacturing

Photopolymerization traditionally involves the use of multifunctional monomers and oligomers thus leading the formation of tridimensional networks. Use of nonfunctional monomers opens the way to the formation of linear photopolymer chains presenting recyclable possibilities. Thermoplastics are generally synthetized by thermal way at high temperatur

Tailoring primary processes for high performance photoinitiating systems usable under visible light

Optimization of holography recording in photopolymers was studied from the point of view of the photogeneration of radicals. On the basis of a dye/borate salt photoinitiating system, the effect of the primary events and their relative efficiency was investigated with respect to the final overall properties, such as the diffraction efficiency. Quenc

Sensitizer – Photoinitiator Interactions II: The sensitization of Phosphine Oxide Photoinitiators

Addition fragmentation chain transfer agents (CTAs) are an upcoming important group of compounds used for controlling radical polymerization.1 Generally, AFCT reagents are known from thermal radical polymerization in solution, photoinitiated, controlled bulk polymerization is rarely found in literature. Transforming an uncontrolled radical chain re
