Abstract
The present disclosure relates to a process for preparing an olefin-acrylate block copolymer, the process comprising: a) performing atom transfer radical polymerization (ATRP) by combining ATRP materials comprising an acrylate monomer, an initiator having a radically transferrable atom or group, a transition metal compound, and a ligand, thereby forming a macroinitiator; and b) combining reaction materials comprising an alpha-substituted acrylate and the macroinitiator, thereby forming the olefin-acrylate block copolymer.
