Photo-induced Polymerization
INTRODUCTION Photo-induced polymerization'-6 is concerned with absorption of ultraviolet radiation to produce an unstable excited species. Subsequent formation of a free radical by rearrangement, fragmentation or energy transfer, followed by attack upon a monomer, leads to polymerization. Yamamoto and Oster7 have indicated that photo-induced polymerization resembles polymerization initiated by ...
متن کاملSynthesis and Characterization of a Novel Borazine-Type UV Photo-Induced Polymerization of Ceramic Precursors.
A preceramic polymer of B,B',B''-(dimethyl)ethyl-acrylate-silyloxyethyl-borazine was synthesized by three steps from a molecular single-source precursor and characterized by Fourier transform infrared (FTIR) and nuclear magnetic resonance (NMR) spectrometry. Six-member borazine rings and acrylate groups were effectively introduced into the preceramic polymer to activate UV photo-induced polymer...
متن کاملPhoto and Radiation Induced Ionic Polymerization
Photo-induced cationic polymerizations of styrene and x-methylstyrene, which are weak electron donors and contain no hetero atom, were carried out in the presence of electron acceptors such as tetracyanobenzene and pyromellitic dianhydride to elucidate the polymerization mechanism initiated through an excited charge transfer interaction. Cyclohexene oxide was also polymerized by photo-illuminat...
متن کاملBenzylpyrazinium Salts as Photo-Initiators in the Polymerization of Epoxide Monomers
In order to study the capability of pyrazinium salt derivatives to act as photo-initiators of epoxide monomers, benzyl pyrazinium hexafluoroantimonate (BPH), benzyl 3,5-dimethyl pyrazine hexafluoroantimonate (BDH) and benzyl quinoxalinium hexafluoroantimonate (BQH) were synthesized by the Menschutkin reaction of benzyl bromide with pyrazine, 2,6-dimethyl pyrazine, and quinoxaline, followed by e...
متن کاملRecent Advances in Photo-Induced Free-Radical Polymerization
Free radical photopolymerization dominates most of the industrial applications of photocuring. The most popular are protective coatings, dental fillings, adhesives, inks, lithography (printing plates), stereolithography but also advanced hightechnology purposes (micro and optoelectronics, holographic data storage, etc.) [1]. Currently, radical photopolymerization is also applied to prepare new ...
