Graft grafting from

Grafting from An active site generated along a polymer backbone starts to propagate monomer and thus produces branches. [Pg.482]

Four types of grafting from processes are distinguished by the mechanism of radical formation. [Pg.385]

Systems examined include copolymerizations of 349 with MMA using RAFT agent 175,548,711 348 with AA using 2207 0 and 348 with 352 using 176.7 4 The latter copolymerization created a precursor for a grafting from reaction by ATRP using the bromoisobutyrate group as an initiator/34... [Pg.559]

The preparation of polymer brushes by controlled radical polymerization from appropriately functionalized polymer chains, surfaces or particles by a grafting from approach has recently attracted a lot of attention.742 743 The advantages of growing a polymer brush directly on a surface include well-defined grafts, when the polymerization kinetics exhibit living character, and stability due to covalent attachment of the polymer chains to the surface. Most work has used ATRP or NMP, though papers on the use of RAFT polymerization in this context also have begun to appear. [Pg.560]

Grafting from silica particles, silicon wafers, and related surfaces usually involves attaching a chlorosilanc or alkoxysilane derivative. Thus alkoxyamincs (e.g, 361,744,749 3627 0) and a wide variety of ATRP initiators (e.g. 363751) have been attached directly to surfaces and used to initiate grafting from" processes. [Pg.562]

Grafting from methods involve creation of metalated sites on a polymer backbone, and subsequent use of these sites to initiate the polymerization of a second monomer. Several examples of such grafting processes have been described 135 ,39>. However, no control of the number and length of the grafts is provided, since some sites may be inaccessible to the incoming monomer. As no accurate characterization... [Pg.168]
