Method for producing rubber composition

Hajime Nishihara, +1 more
TL;DR: In this article, a method for producing a rubber composition crosslinked to a crosslinking degree of 50% or higher by mixing a crosslinkable rubber (A) and a thermoplastic resin (B) and cross-linking the mixture with a cross-link agent (C), wherein the crosslink agent(C) is divided and added in parts to sequentially carry out the crosslink, was presented.
