Abstract
This invention relates to a process for making a vulcanized rubber article comprising the steps of (1) kneading at a temperature within the range of about 70° C. to about 190° C. in a bulk thermomechanical mixer (a) an amino group containing rubbery polymer, wherein said amino group containing rubbery polymer contains from about 0.1 weight percent to about 20 weight percent monomer units containing an amino group, (b) from 0.1 to about 25 phr of an organophilic 2:1 layered silicate clay selected from the group consisting of montmorillonite clays, bentonite clays, hectorite clays, saponite clays, nontronite clays, beidellite clays, fluorohectorite clays, stevensite clays, volkonskoite clays, sauconite clays, and laponite clays, and (c) at least one conventional rubber compounding ingredient selected from the group consisting of curing agents, cure accelerators, cure activators, processing aids, reinforcing fillers, oils, cure retarders, resins, and antidegradants, to produce a mixed compound; (2) discharging the said mixed compound from the bulk thermomechanical mixer; (3) forming the mixed compound into an article; and (4) vulcanizing the article.
