实验步骤: 272 ml. of water, 10 g. of Gelvatol 1-90 polyvinylalcohol and 5 g. of Acrysol WS-32 acrylic polymer were heated until the binders dissolved. 50 g. of stearic acid was then added and melted to form a liquid layer floating on the aqueous solution. 23 ml. of ammonium hyroxide (28% solution), which was the stoichiometric amount to form ammonium stearate, was then added dropwise to the gently stirred liquid. An intractable gel is formed which was transferred to a vigorously-stirred Waring Blendor, and then 20 g. of calcium chloride dissolved in 20 ml. of water slowly added until the mixture became solid. 50 ml. of water was then added with stirring until a creamy paste formed. After drying on a substrate this material gave a pressure-sensitive film with excellent hiding power. The formation of ammonium stearate in situ is the preferred method of preparation because it allows a higher solids content to be obtained and yields smaller particles of calcium stearate. The density of the dry coating was 0.5 g./cc which is equivalent to about 50% void volume. was then added dropwise to the gently stirred liquid An intractable gel is formed which formed After drying on a substrate this material gave a pressure-sensitive film with excellent hiding power the preferred method of preparation because it to be obtained

实验步骤: A lubricant composition was formed by first adding 43.00 gms of oxidized CS-600 low viscosity byproduct wax (viscosity: 11 cps; acid number: 14.7 mg KOH/gram; Mettler drop point: 109.5° C.), 122.50 gms of stearic acid, 15.5 gms of calcium hydroxide and 19.0 gms of glycerol monostearate to a reactor vessel. The combination was melted and held at 140° C. with slight agitation. The calcium hydroxide reacted with the stearic acid, forming a calcium stearate product and water as a byproduct. The high temperatures converted the water to steam, generating foam, and the foam was dissipated by the glycerol monostearate. The mixture was mixed until water formation stopped, and it was slowly stirred to remove any entrapped air. The mixture was then held for a finishing step such as prilling or pastillating. The resulting lubricant composition contained 22.42% of the oxidized byproduct wax, 6.68% residual stearic acid, 9.90% residual glycerol monostearate, and 61.00% calcium stearate. This lubricant composition had an acid number of 23.2 mg KOH/gram and a viscosity of 1900 centipoise at 140° C. A lubricant composition was formed held at 140° C. with slight agitation

实验步骤: 2.98 lb of calcium stearate powder (Hydense 5862, obtained from Mallickrodt), 4.26 lb of Ethanox 330 powder, and 12.76 lb of GMS-40 powder were combined and tumble blended for 3 minutes to obtain a homogenous powder blend. This powder blend was processed with the pellet mill under essentially the same conditions/procedures of Example 1, except the powder feed rate to the pellet mill was bout 47 lb/hr and the die temperature ranged from about 42° C. to about 47° C. The output from the pellet mill consisted of 91.5.% by weight cylindrical pellets of nominally 3 mm diameter, the balance being −12 mesh fines. The pellets thus obtained exhibited good abrasion resistance and therefore would handle well in powder metering and conveying equipment. to obtain a homogenous powder blend ranged from about 42° C. to about 47° C The pellets thus obtained
