Claims (6)
1. Förfarande för avlägsning av restmonomer frän vinyl-kloridhomo- eller kopolymerer, som erhällits medelst mass-polymerisation, där monomerblandningen, som skall avlägsnas, samtidigt som polymerisatet omröres bringas frän polymerisations-trycket tili ett absolut tryck, san ligger under 0,16 bar, och polymeri-satets temperatur höjes tili ätminstone 70°C eller hälles vid en temperatur, san ligger under hano- eller kapolymerens sönderfallstemperatur vid begvnnelse-skedet, och dessa tryck- och temperaturförhällanden uoprätthälles praktiskt taget tili gasavlägsningens slut och polymerisatet bringas i kontakt med vatten sedan koncentrationen av resterande vinyl-kloridmonomer hos homo- eller kopolymeren underskridit 2000 mg/kg, kännetecknat av att tili vattnet, som utgör 0,5-3 vikt-% av homo- eller kopolymeren, tillsätts ätminstone ett anjoniskt ytaktivt ämne.
2. Förfarande enligt patentkravet 1, kännetecknat av att det ytaktiva ämnet är ett alkalisalt av fettsyror med 6-22 kolatomer, ett alkaliskt alkylsulfat, ett alkaliskt alkyl-sulfat med hydroxylgrupper, ett alkaliskt alkylsulfonat, ett alkaliskt alkylarylsulfonat, ett alkaliskt mono- eller dialkylsulfosuccinat, ett alkaliskt mono- eller dialkylfosfat, eller en linjär eller förgrenad alkylgrupp med 4 tili 18 kolatomer.
3. Förfarande enligt patentkravet 2, kännetecknat av att det ytaktiva ämnet är natriumlaurat, natriummyristat, natriumpaImitat, natriumstearat, natriumlaurylsulfat, natrium-tetradekylsulfonat, natriumdodekylbensensulfonat, natriumdodekyl-fenoxibensensulfonat, natrium-mono-oktylsulfosuccinat, natrium-dibutylsulfosuccinat, natriumdihexylsulfosuccinat, natriumdioktyl-sulfosuccinat eller natriumdodekylfosfat.
