Reinforcing styrene butadiene rubber with lignin-novolac epoxy resin networks

open access: yeseXPRESS Polymer Letters, 2015
In this study, lignin-novolac epoxy resin networks were fabricated in the styrene butadiene rubber (SBR) matrix by combination of latex compounding and melt mixing. Firstly, SBR/lignin compounds were co-coagulated by SBR latex and lignin aqueous solution.
