✦ Synopsis

Abstract

Two‐dimensional NMR spectroscopic studies (HECTOR and NOESY) have confirmed that the copolymer of diethyl diallylmalonate with sulfur dioxide consists predominately of cis‐linked cyclopentane rings. When the cyclopolymerization is carried out at 81°C in acetonitrile, the ratio of cis to trans linkages is 4.3 : 1. © 2004 Wiley Periodicals, Inc. J Appl Polym Sci 91: 3477–3480, 2004
