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 کاملInsertion polymerization of acrylate.
Multiple insertions of acrylate in copolymerization with ethylene, and an insertion homo-oligomerization of methyl acrylate were observed for the first time. Key to these findings, and to mechanistic insights reported, are labile-substituted complexes as catalyst precursors.
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 کاملTowards Integrated Continuous-Flow Chemical Reactors
A device for rapid mixing of two solutions is presented. As the main mechanism for mixing is diffusional mass transport, the ̄ow has to be split into several laminae which are narrower than the capillary width. Complete mixing is achieved within a few seconds in a ̄ow-through device with a channel system that is 600mm wide at its narrowest spot.
متن کاملImproving photo-controlled living radical polymerization from trithiocarbonates through the use of continuous-flow techniques.
Herein, we report simple flow reactor designs that enable photo-controlled living radical polymerization (photo-CRP) from trithiocarbonates (TTCs) with significant enhancements in scalability and reaction rates compared to the analogous batch reactions. We also demonstrate the "on/off" photo-switchability of this reaction under flow conditions.
