Reversible addition–fragmentation chain transfer step-growth polymerization with commercially available inexpensive bis-maleimides

Commercially available N -aromatic substituted bismaleimides were used in RAFT step-growth polymerization with a bifunctional RAFT agent, affording polymers having moderate to high molecular weights. This advancement increases the accessibility of our previously reported methodology and allows preparation of graft copolymers in a straightforward manner at significantly larger scale.
