DISPERSIONS OF FIBRES IN RUBBER Abstract of the Disclosure Polymer-fibre mixtures with improved homogenietyof dispersion of fibres throughout the polymer matrix areprepared from fibres prior mixed or coated with aplasticizer which is compatible with both the fibre andthe polymer matrix. Then the plasticizer-fibrecombination can be mixed into the polymer matrix, usingstandard polymer mixing equipment and for reasonablelengths of time, to produce a mixture in whichagglomerations of fibres are very materially reduced.preferred fibre is a fibrillated aramid fibre, dispersionof which in polymers has previously caused particulardifficulties. Suitable polymers include hydrocarbonelastomers such as SBR, for use with which an aromaticmineral oil is a preferred plasticizer, and oil-resistantNBR elastomers, for use with which an ester plasticizersuch as dioctyl phthalate is preferred.
