    摘要： This invention relates to a process for preparing a photosensitive composition having a low heat history which includes:(a) forming a substantially homogeneous dispersion by mixing at least one photoinitiator or photoinitiating system, and at least one binder selected from the group consisting of reactive binders and non-reactive binders in the form of a dispersion provided that when said binder is non-reactive then at least one reactive component is added which is capable of reacting with the photoinitiator;(b) coagulating the dispersion to form a coagulum and a liquid; and(c) substantially removing the liquid to form a photosensitive composition.

    摘要： Incorporating fibrous filler into an elastomer by adding to a screw extruder an aqueous slurry of an organic fibrous filler having a length less than about 25 mm and an elastomer latex, e.g., polychloroprene latex. The latex and slurry are fed to the extruder and the latex is coagulated in the extruder. The coagulated latex containing fibrous filler is fed to a dewatering zone. The flow of coagulated elastomer is restricted so that water present in the coagulated elastomer is separated by means of a vent in the extruder upstream from the restriction and discharging and recovering the fiber-filled elastomer. The compound can be used for the manufacture of power transmission belts.
