This work is an attempt to describe the interaction between regenerated cellulose and nitrile rubber (NBR) as a function of the mixing process in the latex phase, the acrylonitrile content and the amount of cellulose incorporated, The study is based on mechanical properties, crosslink density and rheometric behavior Three types of NBR with 26, 33 and 45% of acrylonitrile and cellulose filler content up to 25 phr were used.
