Abstract
New NLO dye methacrylate-methylmethacrylate copolymers were synthesize d. The NLO-chromophores bound covalently to the polymer chain are: 4-c yano-4'-dialkylamino-alpha-cyano-stilbene, 4-cyano-4'-alkoxy-alpha-cya no-stilbene and 4-cyano-4'-alkoxy-stilbene. Films spincoated from thes e polymers were poled by a positive corona discharge just above T(g) ( as measured by DSC). Nonlinear susceptibilities [X(zzz)(2) of the film s were derived from the analysis of full-angle Maker fringe patterns a t 1064 nm] X(zzz)(2) values as high as 1.43 . 10(-7) e.s.u. could be a chieved.
