摘要： A process for the continuous agglomeration of granular tetrafluoroethylene polymer powders which cannot be processed from the melt to give molding powders having a high bulk density, an improved powder flow and particle stability and a narrow particle size distribution is described. In this process, the powder to be agglomerated is first introduced uniformly into a pretreatment stage and is dispersed and pre-agglomerated in this stage in the liquid agglomeration medium, composed of water and an organic liquid capable of wetting polytetrafluoroethylene, is then agglomerated to the desired average particle diameter in an agglomeration stage and is finally treated further in an after-treatment stage in order to develop the final shape of the particles. Finally, the powder is separated from the liquid medium and is dried. This makes it possible to obtain, in an economical manner and with excellent processing properties, high-grade agglomerated molding powders of such tetrafluoroethylene polymers, in particular of such polymers which have been modifed with small quantities of perfluoro-(alkyl-vinyl) ethers.

摘要： For the thermoplastic processing of polyvinyl alcohol, the processing temperature must be below the decomposition temperature of the polyvinyl alcohol; this is attained by incorporating plasticizers. For preparing a plasticizer-containing granular polyvinyl alcohol wherein the plasticizer is homogeneously distributed, there is used as starting material a granular polyvinyl alcohol consisting substantially of particles having a definite diameter. The plasticizer is incorporated in the presence of a small amount of water insufficient to dissolve the polyvinyl alcohol, and the temperature is adjusted in a definite manner during the mixing operation. Simultaneous presence of fine particles of a high molecular weight organic compound soluble or dispersible in water is advantageous. The plasticizer-containing granular polyvinyl alcohol is suitable for the manufacture of any shaped articles, especially films and sheets.

摘要： A method for coagulating a latex of a synthetic polymer having a coagulated latex particle formation temperature to form substantially spherical particles, the method comprising: forming substantially spherical latex particles by dispersing substantially spherical drops of the latex into a vessel or chamber containing a coagulating atmosphere which can be (i) a gaseous coagulant or (ii) a liquid coagulant in the form of a mist of drops having diameters such that the terminal settling velocity of the drops under free-falling conditions is in accordance with Stokes' Law, while maintaining the coagulant at the coagulated latex particle formation temperature and while causing water at the coagulated latex particle formation temperature to flow downward over the inner surface of the coagulation vessel to cause pluralities of polymer particles in a drop of the latex to coagulate to form substantially spherical coagulated latex particles. Contact is maintained between the spherical drops of latex and the coagulating atmosphere for a time effective to permit said drops to absorb about 0.36 to 8% by weight of coagulant based on the weight of the polymer, to stabilize said drops. The substantially spherical particles are separated and recovered.

摘要： Nontacky, elastomeric shaped objects (e.g., pellets or filaments) comprising a normally tacky, uncured elastomer having an integral, porous coating of silicic or aluminic acid polymer can be prepared by bringing shaped bodies of a normally tacky, uncured elastomer latex into contact with an aqueous bath containing a soluble coagulating salt for the latex, and a silicic or aluminic acid polymer, and washing and drying the resulting coated shaped objects. The shaped objects are highly porous before washing and drying, and some porosity remains even after washing and drying.
