Photo-induced charge-transfer initiation

Reaction Mechanism of Vinyl Polymerization with Amine in Redox and Photo-Induced Charge-Transfer Initiation Systems... [Pg.227]

A substantial number of photo-induced charge transfer polymerizations have been known to proceed through N-vinylcarbazole (VCZ) as an electron-donor monomer, but much less attention was paid to the polymerization of acrylic monomer as an electron receptor in the presence of amine as donor. The photo-induced charge-transfer polymerization of electron-attracting monomers, such as methyl acrylate(MA) and acrylonitrile (AN), have been recently studied [4]. In this paper, some results of our research on the reaction mechanism of vinyl polymerization with amine in redox and photo-induced charge transfer initiation systems are reviewed. [Pg.227]

Graft Copolymerization of Vinyl Monomers Onto Macromolecules Having Active Pendant Group via Ceric Ion Redox or Photo-Induced Charge-Transfer Initiation... [Pg.541]

MACROMOLECULES HAVING AN ACTIVE PENDANT GROUP BY PHOTO-INDUCED CHARGE-TRANSFER INITIATION... [Pg.551]

Therefore, the graft copolymerization of vinyl monomers onto macromolecules having active an pendant group can be achieved either by redox initiation with a Ce(IV) ion or by photo-induced charge-transfer initiation with BP, depending on the structure of the active groups. [Pg.552]

The photo-induced charge-transfer copolymerization entity consists of a donor monomer and an acceptor monomer, without initiator. Reported combinations usually consist of an aryl vinyl monomer as the donor component and a 1,2-disubstituted vinyl monomer as the acceptor component. [Pg.7]

The initiation mechanism of photo-induced charge-transfer copolymerization of donor-acceptor monomer pairs is clarified by integrating the results from organic chemistry and polymer chemistry. A reasonable suggestion for the initiating species in certain cases may be a tetramethylene 1,4-diradical. The excited complex of the donor/acceptor monomers undergoes multiple follow-up reactions to produce the... [Pg.35]

Spontaneous thermal copolymerization is usually observed in strong donor (D)/strong acceptor (A) pairs, for example a-MSt/MAn, because only in these pairs is the charge-transfer interaction strong enough to produce initiating radicals. On the other hand, photo-induced copolymerizations encompass a wider range of donor/acceptor combinations. [Pg.12]
