ABSTRACT: Controlled copolymerization of n-butyl acrylate with 1-octene was achieved by ARGET (activators regenerated by electron transfer) ATRP (atom transfer radical polymerization) in anisole. When a normal ATRP of n-butyl acrylate and 1-octene was conducted, the polymerization resulted in relatively low conversion (
