“…7 One particular type of CRP that has been shown to be robust, versatile and convenient is ATRP. [9][10][11]14 As shown in Scheme 2, the ATRP process begins with the activation of an alkyl halide (or pseudo-halide), RX, by the reversible abstraction of the halogen by a transition metal complex, M t n /L, to form the active radical species, R . , which initiates polymerization.…”

Polyisobutene‐graft‐poly(methyl methacrylate) and polyisobutene‐graft‐polystyrene with controlled compositions and side chain architectures were prepared through atom transfer radical polymerization (ATRP). Poly[isobutene‐co‐(p‐methylstyrene)‐co‐(p‐bromomethylstyrene)] (PIB) was used as a macroinitiator in the presence of CuCl or CuBr as a catalyst and dNbpy as a ligand. The compositions were controlled by the conversion of the monomer with polymerization time. The molecular weight distributions of the side chains were controlled through ATRP in the presence/absence of a halogen exchange reaction. DSC and DMA measurements showed that graft copolymers have two glass transition temperatures suggesting microphase separated behavior, which was also confirmed by SAXS measurements. The phase and dynamic mechanical behaviors were strongly affected by the compositions and/or the side chain architectures. The properties of the graft copolymers were controlled in a wide range leading to toughened glassy polymers or elastomers.

“…Atom Transfer Radical Addition (ATRA) [1][2][3][4] and Atom Transfer Radical Polymerization (ATRP) [5][6][7][8] are two powerful synthetic methods in organic chemistry and polymer chemistry, respectively. In ATRA, R-X (usually an organic halide) adds across the unsaturated carbon-carbon bond of an alkene, M, to form the monoadduct R-M-X in high yield, while ATRP achieves controlled/"living" radical polymerization of vinyl monomers by the repetitive ATRA process to form R-(M) n -X, as shown in Scheme 1.…”
