    • A method for preparing coatings of thin films onto solid particle has been achieved by in-situ simultaneous nucleation and deposition of dissolved material out of a supercritical fluid, resultant film formation on the solid particles suspended in the supercritical fluid, and subsequent thermal conditioning of the coating on the particles. The coating method involves an enclosed system that provides: 1) for suspension of the solid particles to be coated; 2) for dissolution of the coating material in the supercritical fluid solvent; 3) for temperature or pressure swing operations causing film deposition/coating of the suspended solid particles and; 4) additional chemical addition and/or thermal cycles providing for any additional reactions required (such as polymerization).

    • A novel thermoplastic elastomer (TPE) which comprises (i) polymeric A blocks in which there are side chains comprising crystallizable moieties having a melting point Tq, and (ii) at least one amorphous polymeric B block having a glass transition point, Tgs, which is less than (Tq - 10) DEG C. The relative proportions and molecular weights of the A and B blocks can be adjusted so as to produce desired physical properties with comparatively little change in Tq, which depends chiefly upon the nature of the crystallizable moieties, which may be for example n-alkyl groups containing 12 to 50 carbon atoms. The novel TPE's show a sharply reduced viscosity in the region of Tq, and can be melt-processed at temperatures close to Tq. The novel TPE's are useful in the form of compositions, shaped articles and assemblies which comprise one of the novel TPE's and a second component which is mixed with, or surrounded by, or surrounds or otherwise provides a substrate for, the TPE. Preferred second components are explosives and other energetic materials, pharmaceuticals, seeds, perfumes, deodorizers, pest control agents, herbicides, insecticides, fungicides, biologically active materials, agrichemicals, and disinfectants. Second components can be released from such a composition or shaped article by a natural increase in the ambient temperature or by heating the composition or article to a temperature at least equal to Tq by means of heat which is (i) generated artificially or (ii) generated by a mammalian body and/or (iii) is conveyed artificially to the composition, article or assembly.
