Abstract

A low-temperature polymerization catalyst comprises a double salt of a Friedel-Crafts metal with a halogen acid and an organic acid. It may be prepared by treating the metallic halide with the organic acid and boiling out hydrogen halide. Suitable organic acids are formic, acetic, propionic and the enolic form of acetyl acetone. Any Friedel-Crafts metal, particularly aluminium and titanium may be used. The Specification includes examples of the polymerization of isobutylene, styrene, a mixture of isobutylene with 1 per cent of isoprene and vinyl acetate.
