Abstract

Process of polymerization in aqueous suspension of aromatic vinyl monomers characterized by the use of an aromatic vinyl monomer: water ratio one: two, using as a suspension stabilizer, either a copolymer of acrylic acid-2-ethylhexyl acrylate, or hydrocytlcellulose, with concentrations between one and two grams per liter of monomer, or N-vinylpyrrolidone with concentrations between 3.5 and 7.0 grams per liter of monomer, depending on the desired molecular weight; the initiator being lauroyl peroxide with concentrations varying between 10.6 and 21 grams per liter of monomer, depending on the desired molecular weight, using reaction temperatures of 75ºC for times ranging from 5 to 8 hours depending on the desired molecular weight and, after this time, a temperature of 85ºc for one hour.
