✦ Synopsis

Allyl ethers are readily polymerized using a new polymerization reaction termed: transition metal-catalyzed tandem isomerization and cationic polymerization. Employing dicobalt octacarbonyl in combination with organosilanes, polymerization takes place rapidly and exothermically to give high molecular weight polymers. In this first article, the concepts leading to the discovery of this novel type of polymerization are presented along with the results of initial studies.

Alkyl allyl ethers undergo facile thermally induced isomerization to alkyl 1-propenyl ethers in the presence of Group VIII transition metal carbonyl compounds as catalysts. The addition of a silane containing a Si-H bond to these systems results in a catalyst system that is capable of not only isome
