Abstract

Mono-olefines such as propene or butene are polymerized in the presence of a liquid consisting substantially of a mixture of ortho-and pyro-phosphoric acids, the specific gravity of which mixture at 15 DEG C. is above 1,90 and, in particular, between 1,90 and 1,99. Such mixtures are obtained by admixture of the ortho- and pyro-acids or by heating commercial phosphoric acid in vacuo. An example gives the yields of polymer when propene is treated at 170-200 DEG C. and 25-30 atmos. with mixtures of acids having specific gravities between 1,905 and 1,990, corresponding to 32 and 72 per cent pyro-acid respectively.
