Employing transfer-dominated branching radical telomerisation (TBRT) and atom transfer radical polymerisation (ATRP) to form complex polyester-polymethacrylate branched-linear star copolymer hybrids via orthogonal initiation

Consecutive free radical telomerisation and reversible-deactivation radical polymerisation reactions allow formation of branched polyester macroinitiators followed by arm growth leading to high molecular weight polyester-methacrylate star copolymers.
