    Abstract: A process for the preparation of polyacetylenes in which acetylene or a mixture of acetylene with other alkynes is polymerised in a liquid reaction medium by means of catalysts based on salts of nickel or cobalt and alkaline metal borohydrides or alkaline metal aluminium hydrides, where, before the polymerisation, the liquid reaction medium containing the catalysts and acetylene or the acetylene-containing mixture is kept at temperatures of from -100 to -40 DEG C for some time and then heated to temperatures above -40 DEG C and polymerised.
