Vinyl polymerization, 307. Polymerization of acrylonitrile initiated by tetramethyl-2-tetrazene

The structure of the aggregates found in dilute solutions of PVC with tacticity 0,53 in THF has been investigated. It is shown that a model of an aggregate describing it as a composition of 10 to 15 single molecules bound together by a crystalline nucleus, is in accordance with the experimental evidence from light-scattering and GPC analysis.
