Abstract: Process for distillatively separating a mixture containing a vinyl ether of the general formula (I) R1—O—CH═CH2 (I) and alcohol of the general formula (II) R2—OH (II) in which R1 and R2 are each independently a saturated or unsaturated, aliphatic or cycloaliphatic radical having from 2 to 10 carbon atoms, and in which the alcohol (II) has a boiling point which is at least 1° C. higher, measured at or extrapolated to 0.1 MPa abs, than the vinyl ether (I), by a) passing the mixture into a first distillation column and withdrawing, as a top product, an azeotrope containing vinyl ether (I) and alcohol (II) and, as a bottom product, a stream enriched with the alcohol (II); b) passing the azeotrope containing vinyl ether (I) and alcohol (II) from the first distillation column into a second distillation column which is operated at a pressure which is from 0.01 to 3 MPa higher compared to the first distillation column, and withdrawing, as a bottom product or gaseous sidestream in the stripping section, the vinyl ether (I) and, as a top product, an azeotrope containing vinyl ether (I) and alcohol (II); and c) recycling the azeotrope containing vinyl ether (I) and alcohol (II) from the second distillation column into the first distillation column.

Abstract: A method for the production of printable paper by treating the surface of the paper with a polymer, involves using an amphoteric polymer (I) which is obtained by reacting (a) polymers containing prim. and/or sec. amino groups with (b) alkylating agent(s) with at least one acid group, a salt of an acid group or a capped acid group and optionally (c) at least one crosslinker with at least two groups which react with amino groups.
