Hyperbranched polyacrylate copolymers were synthesized by self-condensing vinyl copolymerization (SCVCP) of 2-[(2-bromopropionyl)oxy] ethyl acrylate (BPEA) and methyl acrylate (MA) in the presence of atetrafunctional initiator(THABI).The structures of the polymers obtained were characterized by 1H-NMR and SEC/refractive index (RI)/right anagle laser light scattering (RALLs)/differential viscometer (DV).Molecular weight (MW)
molecular weight distribution (MWD) and degree of branching (DB) were influenced by conversion and initial feed molar ratio of BPEA
MA and THABI.The addition of THABI can narrow the MWDs of the polymers obtained. The results ale consistent with our simulation result.
