Abstract The triblock copolymer poly(methyl methacrylate‐b‐lauryl methacrylate‐b‐methyl methacrylate) {P(MMA‐b‐LMA‐b‐MMA)} has been synthesized by a two stage atom transfer radical polymerization in bulk at near room temperature (ca. 35 °C) using CuCl/pentamethyldiethylenetriamine (PMDETA)/tricaprylylmethylammonium chloride (Aliquat®336) complex as the catalyst and 1,2‐bis (bromoisobutyryloxy)ethane (BIBE) as the initiator for the polymerization of LMA in the first stage. The same catalyst was also used for the polymerization of MMA in the second stage. The dynamic mechanical thermal analysis of a sample with the middle block M n = 82000 and each end block M n = 14500 showed typical features of a thermoplastic elastomer.
