Abstract: A flavour delivery system for tobacco includes a flavour material entrained in a zeolite material and forming a core and a wax material encapsulating the core.

Abstract: A smoking composition includes tobacco material and a flavor delivery system. The flavor delivery system includes a flavor material and first wax material forming a core and a second wax material encapsulating the core. The second wax material being a different wax material than the first wax material.

Abstract: The invention relates to a method of preparation for polymers, particularly binders for powder coatings and powder coatings which are prepared as a solution in a supercritical fluid phase. Binders for powder coatings are prepared from at least two ethylenically unsaturated monomers capable of free-radical or ionic copolymerization, and conventional initiators and regulators in supercritical fluids, whereby polymerization is carried out in the homogeneous phase, and, after the reaction has ended, either the composition or the phase parameters of the mixture are altered so that at least two phases with supercritical fluid are obtained, and the phase containing predominantly polymer is separated and the polymer is separated as a powder from the sc fluid by depressurization or the polymer phase is further processed under supercritical phase conditions to the powder coating.

Abstract: The present invention relates to a process for the production of particles from solutions or melts of heat-activatable polyurethanes by i) dissolving a compressible auxiliary agent at a pressure of between 50 and 1000 bar into a conveyable solution or melt of a heat-activatable polyurethane to obtain a mixture of polyurethane, compressible auxiliary agent and optionally solvent, ii) optionally adjusting of the temperature of the resulting mixture to a temperature of from 40° K below to 150° K above the crystallite melting point of the polyurethane, iii) expanding the mixture by means of an expansion device into a container, while adjusting the temperature in the container to at least 5° K below the softening temperature of the polyurethane to maintain the open jet particles in a form in which they do not agglomerate, and iv) separating the formed particles from the stream of decompressed compressible auxiliary agent and optionally solvent.
