Abstract
Abstract The present invention describes a polymeric nonlinear optical (NLO) material in which NLO active groups are integral to the polymer chain and a process for producing the NLO material. The polymeric NLO material has recurring monomeric units of the following formula: ##STR1## where X is a divalent electron-donating group, Ar is a conjugating group, A is a divalent electron-withdrawing group and n is an integer of at least 3. The NLO material may be, for example, a poly(benzene sulphonamide) or a poly(p-benzamide). The polymeric material is prepared by applying a stress to the NLO polymer to induce orientation of the NLO active groups in the polymer such that the material exhibits nonlinear optical capabilities.
