| 摘要 |
The invention relates to a method for treating polymer components produced by emulsion polymerisation. The inventive method is characterised in that coagulation of the aqueous polymer latex which is present after emulsion polymerisation is carried out using a combination containing A) at least one aqueous solution of a salt selected from sodium chloride, calcium chloride, magnesium chloride, aluminium chloride, sodium sulphate, magnesium sulphate, aluminium sulphate or a mixture thereof, B) at least one aqueous solution of a salt of hypophosphoric acid (H3PO2), phosphoric acid (H3PO3 or HPO2), ascorbic acid or mixtures thereof and optionally C) an aqueously diluted acid selected form sulphuric acid, phosphoric acid or acetic acid. |
