Abstract
Liquid or solid homopolymers of alkenyl alkyl ethers containing at least three carbon atoms in the alkenyl radical are made by polymerizing the ether in the presence of a Friedel-Craft catalyst at a temperature not in excess of 0 DEG C. The ether may be obtained by the acetalization of an aldehyde and an alcohol produced by the catalytic hydrogenation of carbon monoxide and/or by the hydroformylation of olefins and decomposition of the acetal. The polymerization may be effected in bulk, solution, e.g. in hexane, or emulsion. The catalyst may be boron trifluoride alone, or as an addition compound with an ether such as ethyl ether, amyl ether or anisole. The alkenyl alkyl ether may be propenyl propyl ether or propenyl butyl ether. Specification 378,544 is referred to.
