The polymeric main chain having the above repeating structure was synthesized according to the same procedures as described in Example 1. The side chain was synthesized as follows. First, 1 g (0.006 mol) of cinnamic acid was reacted with 0.71 g (0.006 mol) of thionyl chloride in dichloromethane at a temperature of 35° C. for 1 hour to form cinnamoyl chloride. Then, the cinnamoyl chloride was reacted with 0.98 g (0.006 mol) of 4-hydroxybenzoic acid and an aqueous solution of NaOH/DMSO with stirring for 1 hour at a room temperature. The product was again reacted with thionyl chloride in dichloromethane to form a side chain as follows.
