Abstract
Isotactic homopolymers of high optical purity (S)-5-methyl-1-heptene and of 1-heptene have been prepared and studied by 13C n.m.r. The tacticity degree evaluation of the polymers was performed on the basis of skeletal methine or methylene carbon atoms resonances in terms of diads. Conformational properties of both polymers have been investigated and discussed on the basis of n.m.r. dynamic parameters.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
