Abstract
An aldehyde of formula <FORM:0911819/IV(a)/1> where R is an aliphatic or aromatic radical or a halogen substituted aliphatic or aromatic radical, is polymerized at below room temperature using as catalyst a metal alkoxide of formula Me(OR)x where M is a metal of valency x and R is an aliphatic or aromatic radical the two R not necessarily being the same when X is greater than one. Specified aldehydes are acetaldehyde, propionaldehyde, butyraldehyde, monodi- and tri-chloroacetaldehydes, and benzaldehyde. Specified alkoxides are aluminium isopropoxide, titanium tetraethoxide, sodium ethoxide, magnesium, calcium and zinc diethoxides and ferric triethoxide. A solvent, e.g. hexane, may be used. An apparatus in which aldehyde vapour is brought into contact with the catalyst is described. Specification 766,629 is referred to.
