実験手順

Synthesis of formazan monomer used copolymers E34, E35, E36, E37 of table 1, infra. ##STR6## Potassium carbonate (24.0 g, 173.9 mmol) was added to an ethanolic solution containing salicylaldehyde (19.0 g, 155.7 mmol) an allyl bromide (22.0 g, 181.8 mmol). The resulting suspension was heated to reflux overnight. The precipitated inorganic salt was filtered off. The filtrate was evaporated under reduced pressure to give the desired product, 2-allyloxy-benzaldehyde.
