Radical polymerization of three fumarates, ethyl 4-(4-methoxyphenylazo)phenylfumarate (1), ethyl 6-hexyl fumarate (2), and ethyl 11-undecyl fumarate (3) was carried out in benzene.Monomers 2 and 3 polymerize to give nematic polyfumarates , while monomer 1 gives no polymer.From the copolymerization of monomer 2 (M2) with styrene (M1) the monomer reactivity ratios r1 and r2 were found to be 0.60 and 0.06, respectiviely.The copolymerization of monomers 2 and 3 was also carried out in an attempt to obtain a guest-host system .The rate of isomerization from trans- to cis-azobenzene was found to be 0.038 min-1 for poly(2/3).
