摘要：

The synthesis of 4-vinyl-1,2-phthalate esters via Suzuki coupling is described, followed by nitroxide-mediated polymerization to prepare short homopolymers (degree of polymerization [DP] = 1040, polydispersity index [PDI] = 1.11.3). Random copolymers with n-butyl acrylate (NBA) were prepared. Copolymers rich in phthalate ester residues of medium lengths (DP = 1648, PDI = 1.21.8) and of shorter lengths (DP = 817, PDI = 1.21.3) were prepared. Copolymers rich in NBA residues were also prepared (DP = 1319, PDI = 1.21.3). All polymers were oily liquids, with glass transitions temperatures undetected between 75 and -40 degrees C, indicating these polymeric phthalates hold promise as potential nonmigratory phthalate plasticizers.
