Elongated granules of reinforcing fibers extending generally parallel to each other longitudinally within the granule substantially uniformly dispersed throughout a film forming latex binder composition. The granules provide complete dispersion of the fibers during their processing conserving physical properties of the fibers and provide improved handling and molding characteristics.

Molding granules, their manufacture and their use in the production of

For use as an emusifier for emulsion polymerization of acrylate monomer mixtures, there is provided a novel mixture of soluble salts of sulfosuccinate half esters of two or three alcohols, each selected from a different class defined and each respective half ester being present in a defined range of proportions in the mixture. The defined emulsifiers, even when used at concentrations less than usual for emulsion polymerization, produce acrylate latex products having a favorable combination of several advantageous properties, particularly good mechanical stability and low viscosity, even when a cross-linking monomer is included in the monomer mixture to be polymerized.
