Abstract
A process for preparing a master batch, comprising: the step of filtrating a dispersion of cellulose nanofibers under pressure or under reduced pressure with a filtration pressure differential of 0.01 MPa or more; and the step of mixing cellulose nanofibers obtained by the filtration step and rubber component is provided. A master batch can be provided to provide a rubber composition with improved mechanical strengths by the invention.
