ABSTRACT:
A polymer comprising structural units of the formula I has a number average molecular weight of less than 300.103g/mole and a weight average molecular weight of less than 500.103g/mole. A preferred example is a polyphenylene-vinylene. A composition of this polymer can be deposited on a substrate by means of inkjet printing excellently. This can be used for the manufacture of electroluminescent devices, in particular multicolor electroluminescent devices
