Preparations based on aziridino polyethers and the use thereof

A process for the preparation of a composition, comprising:

• providing a catalyst component K comprising an initiator selected from the selected from the group consisting of an oxonium salt, an ammonium salt, a sulfonium salt, p-toluenesulfonic acid, zinc salt of p-toluenesulfonic acid, dodecylbenzenesulfonic acid salt, and combinations thereof;
• and
• preparing basic component B by a process comprising mixing two components Z1 and Z2 together,
• wherein component Z1 comprises at least one polyaddition product or at least one polycondensation product having on average 2 aziridino groups or more and a molecular weight of at least 1000, with the proviso that component Z1 does not comprise polydimethylsiloxanes, and
• wherein component Z2 comprises at least one compound having only 1 aziridino group, and at least one compound according to component Z2 differing, in its chemical make-up, from at least one compound according to component Z1 in at least one further feature other than the number of the aziridino groups, the difference from component Z1 comprising at least one or two or more of the following further features:
• i) number average of the molecular weight,
• ii) weight average of the molecular weight,
• iii) polydispersity,
• iv) composition of the polymer backbone, and
• v) end groups, and
• wherein mixing two components Z1 and Z2 together comprises mixing an amount of component Z2 that is about 0.4% by weight to about 25% by weight, based on the total weight of components Z1 and Z2.
