    摘要: A high refractive index, curable, synthetic resin composition comprising a core resin composition composed of a mixture of ethylenically unsaturated compounds, and an initiation system containing both photo and thermal initiators, particularly a photochromic resin composition which further includes at least one photochromic dye. Also a curing process, which includes a combination of multi-step radiation curing and thermal annealing. Articles produced of cured composition exhibit superior physical and, in appropriate cases, photochromic properties and can be easily mass produced on a commercial scale due to short processing time and use of readily available chemicals.

    摘要: In order to produce mineralic bodies of high porosity, usable inter alia as adsorbers, purifiers and catalyst carriers, a predominantly mineralic mass with organic admixtures--both preferably obtained from industrial waste products--are subjected to a three-phase treatment. In a first phase, the mass is heated in an inert or reducing atmosphere to a sintering temperature between about 1000.degree. C. and 1350.degree. C. whereby the organic constituents are carbonized and partly penetrate the consolidating mineralic structure. In a second phase, still under the same nonoxidizing atmosphere and at the sintering temperature referred to, the mineralic structure is sintered into a coherent matrix. In a third phase, with reduction of the temperature to a lower level between about 600.degree. and 1000.degree. C. and exposure to the atmosphere, the carbonaceous substances occluded in the mineralic skeleton are burned off to increase its porosity.
