Abstract

1519227 Vinyl chloride monomer recovery BASF AG 17 Oct 1975 [24 Oct 1974] 42647/75 Heading C3L Vinyl chloride monomer is recovered from an aqueous settling dispersion of vinyl chloride polymer by mechanical dehydration followed by treating the moist polymer at 40-140‹ C. while purging with steam; monomer is recovered from the effluent steam and the treated polymer is dried. The dispersion may be a suspension polymer or a coagulated latex.
