Novel high performance thermo� and photo�reversible networks utilizing both a Diels-Alder reaction and photo�dimerization of crosslinkable anthracene groups were investigated. Well�defined copolymers with 9�anthrylmethyl methacrylate (AMMA) and other alkyl methacrylates such as methyl methacrylate (MMA) and 2�ethylhexyl methacrylate (EHMA) having different AMMA compositions were synthesized using RAFT techniques. Well�controlled block copolymerization of AMMA and alkyl methacrylates was also successfully accomplished by using a trithiocarbonate�terminated poly(alkyl methacrylate) macroCTA at 80 �C.

Thermo� and photo-reversibility studies of the copolymers from Diels-Alder modification and photo-dimerization will be also discussed.
