Abstract

A process for the preparation of acetylene copolymers by catalytic polymerization of a mixture of acetylene and dialkynes or polyalkynes, using Ziegler catalysts. The novel polymers may be used as colored pigments, as colored coatings for metal, glass or plastics, and for the production of electrical or magnetic components.
