    • The powdery composition based on water-soluble polymers essentially contains a) 5 to 95 wt. % of a water-soluble polymer which is made up of sulfonates of lignin and/or sulfonated melamine-formaldehyde, naphthalene-formaldehyde and/or ketone-formaldehyde condensation products, and b) 5 to 95 wt. % of a fine particle mineral support material with a preferred specific surface area of 0.01 to 500 m2/g. Calcium carbonate, dolomite, clays, fly ashes, Portland cements and gypsum are suitable typical support materials and for this purpose should preferably have a particle size of 0.1 to 1,000 nullm. Also claimed is a process for the production of this composition, wherein the water-soluble polymer is above all incorporated into the particular support material, which in particular takes place in the form of an aqueous solution in a least one step and can also involve intermediate drying steps. These compositions are used in amounts of 0.05 to 5 wt. % of polymer in building materials such as bitumen products, cement, calcium-based building materials and/or oil field building materials, during which they can also be combined with other building material additives and filler admixtures. The powdery compositions are characterized inter alia by their very good pourability, they are tack-free and extremely easy to meter in and to process and favorably influence product properties such as flowability.

    • The present invention provides a process for producing a phenolic resin-made pulley having a metal insert embedded therein, which process comprises: setting a metal insert in the form of a cylinder or a circular solid shaft in a cavity of a mold having a movable side die, a fixed side die and the cavity, closing the mold in a state in which a part or the whole of the movable side die has been moved backward by a given distance from its predetermined position to be taken when a pulley to be produced has a final shape, injecting a phenolic resin molding material into the cavity to fill the cavity with the molding material, preferably sealing a gate of the mold with a gate-sealing pin, and substantially simultaneously with or after the gate sealing moving forward the part or the whole of the movable side die moved backward, to said predetermined position to mold a phenolic resin-made pulley. This process is particularly effective to mold a phenolic resin-made pulley having holes formed in its disc portion. Said pulley can be produced according to the above process, for example, by closing the mold in a state in which pins used for forming said holes have been moved backward from their predetermined positions to be taken later, injecting a phenolic resin molding material into the cavity to fill the cavity with the molding material, preferably sealing a gate of the mold with a gate-sealing pin, and substantially simultaneously with or after the gate sealing moving forward the pins to said predetermined positions to mold said pulley. The present invention also provides a phenolic resin composition suitably used in the above process for pulley production.
