    摘要: An oxygen absorption composition without requiring moisture in oxygen absorption which comprises an oxygen absorbent comprising, as a principal component, an oligomer in liquid form having an unsaturated group, a number-average molecular weight in the range of 150 to 4,000 and a viscosity in the range of 100 to 4,000 cP such as butadiene oligomer in liquid form and an oxygen absorption-accelerating substance, being supported on a carrier; and an other gas absorbent. The principal component may be replaced with an oligomer in liquid form having an unsaturated group and being incorporated with an oxygen-unabsorptive diluent to adjust the viscosity of the mixture to 10 to 4,000 cP. The composition is enhanced in oxygen absorption capability in every preservation atmosphere from a low humidity to an intermediate and high humidity, easily producible, minimized in gas generation after oxygen absorption and almost free from odor.

    摘要: A cured matter obtained by polymerizing and curing a polymerizable composition comprising a compound having at least one episulfide in a molecule is reduced in an odor by adding a perfume to the polymerizable composition comprising the compound having at least one episulfide in a molecule. A cloudiness of the lens is removed by raising a purity of sulfur to 98% or more. A reduction in a chlorine content of the sulfur compound described above to 0.1% by weight or less elevates an oxidation resistance and a light fastness of the high refractive index optical material and improves a color tone thereof. An optical product having a high refractive index and a high-degree transparency is provided by subjecting the composition in advance to deaerating treatment at 0 to 100° C. for one minute to 24 hours under a reduced pressure of 0.001 to 50 torr.
