METHOD FOR PRODUCTION OF DIMMERS OF α-METHYLSTYRENE Russian patent published in 1997 - IPC

Abstract RU 2074161 C1

FIELD: production of polymer materials. SUBSTANCE: dimerization of a-styrene is carried out in batch or flow reactor. The process takes place in the presence of vanadium pentoxide being supported on titanium or aluminium oxide, quantity of said vanadium pentoxide being 2-10 mass %. Linear DIMMERS are selectively prepared at 80-100 C, cyclic DIMMERS being prepared at 130-150 C. EFFECT: improves efficiency of the method. 3 cl
