Acrylic Acid → 5-Phenyl-2,4-pentadienoic acid

Participants

Reaction Steps

First, an 80/20 styrene-acrylic acid copolymer was prepared by the emulsion copolymerization of 49.09 g of styrene with 14.7 g of acrylic acid. Sodium lauryl sulfate was used as the surfactant (1.53 g), potassium persulfate (0.17 g) as the initiator and ammonium hydroxide (dropwise) was used to adjust the pH to 4. Deoxygenated water (165 g) was used as the continuous phase. After polymerization, the material was found to contain both acrylic acid and styrene by FI-IR. This emulsion was found to contain 22% solids by weight.
