Amination of some chloromethylated polymers with 4-(dimethylamino) cinnamic acid

The amination reaction of chlorometylated polystyrene and polysulfone with 4-(dimethylamino) cinnamic acid was studied. The resulting polymers are ins oluble in DMF due to the presence of quaternary ammonium:groups which facil itate the aggregation of photoactive cinnamoyl groups and consequently thei r photocyclodimerization. Also, low molecular weight quaternary compounds w ere synthesized by the amination reaction between chlorometylated derivativ es (benzyl chloride, allyl chloride, respectively) and 4-(dimethylamino) ci nnamic acid or 4-(dimethylamino) cinnamic benzyl ester.
