Copolymer from the waste products of styrene and maleic acid production

Influence of the process conditions on the production of “STAM” copolymer from waste products formed at join producing of styrene and propylene oxide, the acetophenone bottom residue at styrene rectification, with maleic acid. Effects of temperature, copolymerization process duration, weight ratio of acetophenone bottom residue to maleic acid and styrene content in the bottom residue are studied.
