Abstract: Tablets for treating and disinfecting water, particularly for water of swimming pools and spas comprising a halogenated derivative of isocyanuric acid together with a volatile additive, chemically incompatible with the latter, encapsulated in a microporous or mesoporous material which has a certain pore size, pore volume and a specific surface. The tablets are chemically stable, while maintaining the expected activity of both the halogenated derivative of isocyanuric acid and the additive.

Abstract: The present invention describes a reinforcing filler for rubber comprising the synergistic combination of precipitated silica with a pore structure defined by a maximum between 25 nm and 35 nm, a total pore volume between 1.3 cm3/g and 1.6 cm3/g, and a compression factor between 1.3 10?2 and 2.3 10?2 MPa?1, and at least one crystalline alkaline silicate corresponding to the general formula of the crystalline alkaline silicates, said crystalline alkaline silicate being swelled and/or layered in the presence of an organic cationic compound in the form of ammonium salt of the +NR4 type according to the formula [CnH2n+1N(CH3)3]+. The rubber formulation obtained by this reinforcing filler composition does present a great reduction of energy dissipated in the tread without compromising the abrasion resistance and elastic modulus properties.

Abstract: A process for the additivation of synthetic fibers, artificial fibers and polymers conferring special properties to them, the process comprising the following steps: the encapsulation of an additive in the pores of a porous material; the incorporation of particles of the porous material (capsules) into the polymer matrix of the fiber; and spinning of the fiber; the capsule withstanding the temperatures and other conditions of the different manufacturing processes which the fibers might undergo and the introduction of the additive into the polymer matrix thereof, characterised in that the porous material is a metal oxide, a zeolite, an aluminophosphate, clay, a carbon material, a hybrid organic-inorganic material or a porous polymer.
