Abstract
We synthesized new copolymer which contains the monomer resulting from the reaction of m-isopropenyl-α,α-dimethylbenzyl isocyanate (m-TMI) with chromophore and m-TMI blocked with butanone oxime. We anchored 4′-[(6-hydroxyhexyl)methylamino]-4-nitroazobenzene as a second-order nonlinear optical active chromophore. After regeneration of isocyanate following thermal dissociation of butanone oxime, we investigated the inter-or intra-molecular crosslinking reaction between the secondary amine in carbamate and regenerated isocyanate. This crosslink reaction was traced via in-situ FT-IR spectroscopy method. Also, we synthesized the non-crosslinkable copolymer which bears methylmethacrylate and monomer with same chromophore used above. After poling the sample, we calculated the order parameters and investigated its relaxation behavior at 100 °C.
