Raman spectroscopy and thermal analysis of gum and silica-filled NR/SBR blends prepared from latex system
Natural rubber/styrene-butadiene rubber (NR/SBR) blends, with and without silica, were prepared by co-coagulating the mixture of rubber latices and various amounts of well-dispersed silica suspension. An attempt to predict blend compositions was made using Raman spectroscopy in association with diff...
