HCID 737775-Phenyl-2,4-pentadienoic acid

Procedure

432 g of propyleneglycol monomethyl ether acetate and 13 g of azobisisobutyronitrile were poured into a five-necked reaction vessel having a capacity of one litter. Then, while introducing nitrogen gas into the reaction vessel, the resultant mixture was heated to 80° C. Then, a mixed liquid constituted by 98.9 g of styrene and 9.1 g of acrylic acid was added drop-wise to the above mixture taking two hours. 30 minutes after finishing of the dropping of the mixed liquid, 6.5 g of azoisobutyronitrile was added to the resultant mixture and the mixture thus obtained was heated for 5 hours to obtain a styrene-acrylic acid copolymer. The weight average molecular weight of the styrene-acrylic acid copolymer thus obtained was 3100.
