Abstract: Curative, cosmetic compositions having healing and remedial properties on skin afflictions such as acne and burns when applied topically to humans. The compositions are formed by contacting the extrudate of a citric acid containing fruit with the mother of pearl portion of a mollusk shellfish.

Abstract: Intimate mechanical blends of polypivalolactone resins of different molecular weights wherein parts molded from the mechanical blends have improved resistance against warpage without diminution of other important physical properties of the higher molecular weight resin.

Abstract: Intimate blends of polypivalolactone resin and polycarbonate resin enable the production of molded articles exhibiting low warpage properties.

Abstract: In the first step of a two step process, PCl.sub.3 and Cl.sub.2 are reacted in a suitable medium. In the second step, PCl.sub.3, Cl.sub.2 and NH.sub.3 are concurrently fed into said medium while keeping the temperature at 100.degree. C. to 140.degree. C. The feeds of the reactants are controlled so that until the first 1/2 of the NH.sub.3 has been reacted the molar ratio of PCl.sub.3 :NH.sub.3 (including the PCl.sub.3 of the first step) is kept above 2. Thereafter, the feeds are adjusted so that with respect to the total amount of ammonia, said molar ratio is between 1.2 and 1.5. Linear phosphonitrilic chloride oligomers having a number average degree of polymerization from 2 to 9 are produced in high yield.

Abstract: Flame retardant thermoplastic compositions containing polypivalolactone resin, an inorganic phosphate, and optionally a fiberglass filler and a polybrominated aromatic compound.
