Thermo� and photoreversible polymers containing anthracene groups for subsequent Diels-Alder reaction and photodimerization were investigated as novel high performance reversible networks. Controlled radical polymerization of 9�anthrylmethyl methacrylate (AMMA) was successfully accomplished using RAFT techniques. Well�defined poly(9�anthrylmethyl methacrylate) (PAMMA) having narrow molecular weight distribution (PDI < 1.2) was obtained using 2�cyano�2�propyl benzodithioate (CPBD) and AIBN as a chain transfer agent and an initiator, respectively, in DMF at 80 �C. AMMA and MMA copolymers having different AMMA compositions were also synthesized at the same conditions for homopolymerization of AMMA. It was found that glass transition temperatures of the polymers were in the range of 119�163 �C depending on the AMMA composition as predicted using the Fox equation, and 5 wt% decomposition temperatures were 240�270 �C. Thermo� and photoreversiblity studies of PAMMA and polymers from Diels-Alder modification and photodimerization will be also presented.
