Polymerization, grafting methods available

Graft copolymers containing styrene in the main chain and other monomers in their side chains are available by numerous methods, including conventional radical [171], controlled radical, anionic [174], and cationic [175] polymerization and by copolymerization of macromonomers [80,174], Grafting methods via conventional radical polymerization are reviewed by Nuyken and Weidner [171], The following reaction scheme demonstrates the principles and universality of the methods applying polymeric initiators ... [Pg.101]

Graft polymerization can be accomplished provided that active sites are available on the surface for reaction with monomers. Two fundamental methods of creating... [Pg.159]

Statistical, gradient, and block copolymers as well as other polymer architectures (graft, star, comb, hyperbranched) can be synthesized by NMP following the approaches described for ATRP (Secs. 3-15b-4, 3-15b-5) [Hawker et al., 2001]. Block copolymers can be synthesized via NMP using the one-pot sequential or isolated macromonomer methods. The order of addition of monomer is often important, such as styrene first for styrene-isoprene, acrylate first for acrylate-styrene and acrylate-isoprene [Benoit et al., 2000a,b Tang et al., 2003]. Different methods are available to produce block copolymers in which the two blocks are formed by different polymerization mechanisms ... [Pg.327]
