Abstract
In the production of polymeric p-phenylene ethylene by condensation of the vapours from the pyrolysis of p-xylene, condensation is effected in the presence of an organic liquid boiling above 250 DEG C. The liquid may be at 30-50 DEG C. and contain a substance known to polymerize vinyl compounds. In examples: (1) p-xylene is passed at 15 mm. through a cylindrical vessel at 940 DEG C., with a contact time of 0.309 sec., and the vapours led through a conduit heated to 100 DEG C., into a vessel containing dibutyl phthalate at 40 DEG C.; (2) and (3) benzoyl peroxide or azo-bis-isobutyronitrile is dissolved in the dibutyl phthalate; (4) the vapours obtained as in (1) are passed into a tube down the walls of which paraffin slowly flows, a film of polymer forming on the walls.
