POLYMER HAVING ALDEHYDE GROUPS, CONVERTING AND CROSS-LINKING OF SAID POLYMER, CROSS-LINKED POLYMER, AND ELECTROLUMINESCENT DEVICE COMPRISING SAID POLYMER

摘要

The present invention relates to a polymer comprising at least one structural unit comprising at least one aldehyde group, and to a method for producing a cross-linkable or cross-linked polymer using a polymer comprising aldehyde groups. The present invention thus further relates to a cross-linkable and a cross-linked produced by means of the method according to the invention, and to the use of said cross-linked polymer in electronic devices, in particular in organic electroluminescent devices known as OLEDs (OLED = Organic Light Emitting Devices).
