Swelling-deswelling behavior and viscoelastic properties of the PU filled NR vulcanizates were investigated. The results showed that the degree of swelling of the PU filled NR vulcanizates reduced as the reinforcement between the filler and rubber increased. The reinforcement improved as particle size and moisture content of the PU filler were reduced ER -
