Methods for the synthesis and polymerization of alpha,alpha'-dihalo-p-xylenes

摘要

The present invention describes an improved method for the polymerization of alpha,alpha-dihalo-p-xylene's such as the alpha,alpha'-dihalo-2-methoxy-5-(2-ethylhexyloxy)-xylene's. The procedure for synthesis is based on the specific order of addition of reagents and the use of an anionic initiator that allows control of the molecular weight of the polymer. The molecular weight control allows processability of the polymer which is important for its utility in applications including in light-emitting-diodes, field effect transistors and photovoltaic devices.
