  • Patent number: 4458029
    Abstract: Polymerizable liquid synthetic resins, liquidreactive constituents of synthetic resins or liquid additives for plastics, in each case containing mineral fillers, are converted to dry, pourable mixtures by mixing with 0.25-5% by weight of a crystalline synthetic calcium silicate, which can be in diverse stages of hydration and has a high length/width ratio and width dimensions of less than 1 .mu.m, it being possible, by this means, to employ the resins not only as casting resins but also as compression moulding resins and adhesives. In addition, handling and processability are improved.

  • Patent number: 4442017
    Abstract: Additives, such as stabilizers, antioxidants, antistatic agents etc., are intimately blended with an irradiation-responsive substance, such as an optical brightener, and incorporated in a thermoplastic polymeric material which is then subjected to irradiation to determine the degree of uniformity of distribution of the additive-brightener blend.

  • Patent number: 4440738
    Abstract: Stable compositions, useful as technetium-99m-based imaging agents, comprise reductic acid or certain structurally-related compounds in combination with a pertechnetate reductant or dissolved in pertechnetate-99m solution. The compositions are especially useful, in combination with a phosphate or phosphonate bone-targeting carrier, for skeletal imaging.

  • Patent number: 4255301
    Abstract: Stabilizer compositions comprising a polymer stabilizer and a carbonate ester of cyclic dihydroxy compounds protect synthetic resins against the harmful effects of light having a wavelength less than 400 nanometers. The carbonate ester can be represented by the formula ##STR1## in which a is a number from 1 to 50, A is hydrogen or ##STR2## B is R' or --G--OH, R and R' are independently alkyl, alkoxyalkyl, cycloalkyl, aryl, aryloxyalkyl, aralkyl, or alkaryl groups, and G in at least one occurrence is a residue of a cycloaliphatic or non-aromatic oxygen heterocyclic dihydroxy compound having 3 to 20 carbon atoms and 1 or 2 rings of 3 to 12 members, of which up to 4 can be oxygen. Additional occurrences of G can be aliphatic glycol or bisphenol residues if desired.
