Resumo
Natural trans- and cis-polyisoprenes and mixtures of these polymers were analysed by near-infrared spectrophotometry. The relative absorptivity data versus the amount of isomers in synthetic mixtures showed a non-linear behaviour. The results are compared with literature data from polyisoprenes extracted from other vegetal species. (C) 2000 Elsevier B.V. Ltd. All rights reserved.
