POLYMER

摘要

The invention relates to a polymer which can be obtained in a multi-stage polymerisation process. In the first stage of said process, polymerisation is carried out in the aqueous phase of at least one ethylenically monofunctional compound, optionally with at least one ethylenically difunctional or multifunctional compound in the presence of a polyesterpolyol, polyurethane and/or a polyacrylate; in the following stage, the resulting product is reacted with at least one ethylenically monofunctional compound, optionally with at least one ethylenically difunctional or multifunctional compound; the resulting product is subsequently reacted with a cross-linking agent. The invention also relates to the utilisation of said polymer.
