    摘要: Disclosed is an alumina-silica resin additive consisting of amorphous alumina-silica particles in which a definite cubic or spherical shape is retained in primary particles and the particle sizes of both the primary particles and the secondary particles are controlled to very small values. This additive is excellent in dispersibility in a resin, non-blowing property, slip characteristic and anti-blocking property. A product obtained by surface-treating the amorphous alumina-silica particles with a certain amount of an organic lubricant is very valuable as a filler.

    摘要: Disclosed to a stabilizer composition for a chlorine-containing polymer, which comprises a zeolite type stabilizer; calcium hydroxide or magnesium hydroxide, a metal soap type stabilizer and perchloric acid as indispensable components.The stabilizer composition is obtained by adding a metal soap type stabilizer to a mixture of a zeolite type stabilizer and calcium hydroxide or magnesium hydroxide under attrition to cover the mixture with the metal soap type stabIlizer at a high efficiency, and adding perchloric acid to the covered mixture.In the stabilizer composition of the present invention, the initial discoloration, which is a fatal defect of the conventional zeolite type stabilizer for a chlorine-containing polymer, can be prevented, and a sufficient hydrogen chloride-capturing capacity is exerted and a high heat stability is attained without occurrence of bleeding.

    摘要: Disclosed is a process for the preparation of a zeolite slurry being excellent in either the static stability or the dynamic stability and having a good flowability, which comprises neutralizing an aqueous cake or slurry containing water and zeolite in such a state that both are substantially inseparable from each other by filtration, with an inorganic or organic acid or an acid anydride or acidic salt thereof so that the pH value of the zeolite slurry at the time of completion of addition of said acid, acid anhydride or acidic salt is in the range of from 9.5 to 12 and the pH value of the zeolite slurry in the stationary state after addition of said acid, acid anhydride or acidic salt is in the range of from 11.3 to 12.7, adding a water-soluble or water-dispersible organic polymeric dispersant in an amount of at least 0.1% by weight based on the anhydrous zeolite to the neutralized zeolite slurry, and subjecting the resulting slurry to highly shearing stirring.
