ABSTRACT:
Vinyl chloride is polymerized in suspension using as the suspension stabilizer a copolymer of 65-85 molar percent of 2-isopropyl-.DELTA..sup.2 -oxazoline and 35-15 molar percent of 2-methyl-.DELTA..sup.2 -oxazoline, having a viscosity number of 35-80 ml/g, measured at 25.degree. C. in an isopropanol/water mixture (50 volume percent of isopropanol) in a concentration of 0.5% (weight/volume of solution).
