Abstract

Saturated aldehydes containing two or more carbon atoms are polymerized at below 40 DEG C. in an aromatic or aliphatic hydrocarbon solvent using complexes or reaction products of organometallic compounds of elements of Group I to III and halides or oxides of elements of Groups II to VI as a catalyst system in the presence of an olefin. The olefin may be added to the other components of the catalyst system before or at the same time as the aldehyde monomer. Acetaldehyde is the specified aldehyde while ethylene, propylene, n-butene-1, n-pentene-1, n-hexene-1, styrene, butadiene and isoprene are specified olefins. Long lists of organometallic compounds and the halides and oxides are given. In examples: (1) aluminium triethyl and titanium tetrachloride and (2) lithium isobutyl and titanium tetrachloride are used.
