Description
Summary:In this article a mechnical spectroscopic study of a series of low (≃8%) and medium (≃ 70%) vinyl‐content polybutadiences, some of them functionalized with 4,4′‐bis(diethylamino)‐benzophenone, is presented. Characterization of polymers with well‐known structure by small‐amplitude oscillatory shear flow enabled investigation of the effect of the vinyl content and functional groups on the rheological behavior of the samples in the linear viscoelastic region. The Doi–Edwards viscolastic model, without any adjustable parameter, proved to be adequate to describe the relationship between the macro/micro structure of the polymers and their viscoelastic properties. Results indicate that the vinyl content and functional groups modify the rheological behavior extensively. © 1995 John Wiley & Sons, Inc.
