Abstract
ESR studies and analysis of the products from the cyclopolymerization of substituted diallylamines show that the cyclization may not involve a concerted process, and that the proportion of piperidine rings formed is increased by the use of bulky or conjugated β-substituents, or increased reaction temperatures, factors which favor thermodynamic control of the direction of ring closure. Increased piperidine ring content causes a small reduction in the basicity of the polymers.
