Improvements made to the processes for the polymerization of methyl methacrylate and vinyl acetate, using a trialkylaluminium and oxygen

摘要

Polymerization of methyl methacrylate, styrene or vinyl acetate is effected in the presence of an aluminium tri (lower alkyl) and oxygen. Aluminium alkyls specified are aluminium triisobutyl, trimethyl, triethyl, tripropyl, triisopropyl, tributyl, triamyl, triisoamyl, trihexyl, triisohexyl, triheptyl and trioctyl. The reaction may be performed in an inert solvent such as pentane, hexane, cyclohexane, n-heptane, octane, benzene, xylene and toluene.
