Controlled/living radical polymerization: Features, developments, and perspectives

This paper presents a review of living radical polymerization achieved with thiocarbonylthio compounds [ZC(=S)SR] by a mechanism of reversible addition–fragmentation chain transfer (RAFT). Since we first introduced the technique in 1998, the number of papers and patents on the RAFT process has increased exponentially as the technique has proved to be one of the most versatile for the provision of polymers of well defined architecture. The factors influencing the effectiveness of RAFT agents and outcome of RAFT polymerization are detailed. With this insight, guidelines are presented on how to conduct RAFT and choose RAFT agents to achieve particular structures. A survey is provided of the current scope and applications of the RAFT process in the synthesis of well defined homo-, gradient, diblock, triblock, and star polymers, as well as more complex architectures including microgels and polymer brushes.

Micellization of block copolymers

A free-radical polymerization process for making macromonomers having structure (1), comprising contacting: (a) CH2=CHY; (b) optionally, CH2=CXB; and (c) free-radicals, produced from a free-radical source; in which B, U, X, Y, Z, m, n and p are defined in the text; macromononer quality being controlled by adjusting one or more of the following variables: molar ratios of a, b and c; temperature; monomer concentration; and conversion.

Polymerized Ionic Liquid Block Copolymer Electrolytes for All-Solid-State Lithium-Metal Batteries

Four different approaches to the synthesis of polyamideimides, which employ aqueous imidization, were studied in order to assess the viability of their preparation in water. Building on previous st...
