    摘要: Describes a polymerizable organic composition comprising a polyol(allyl carbonate), e.g., diethylene glycol bis(allyl carbonate), and from 0.1 percent to 10 percent by weight, based on the total weight of the composition, of an allyl ester terminated nonaromatic polyester, e.g., diallyl 4-methyl-1,2-cyclohexanedicarboxylate oligomer with 1,4-butane diol. Polymerizates prepared from polymerizable organic compositions of the present invention have a refractive index of less than 1.53, e.g., from 1.49 to 1.50, and are substantially free of defects due to tinting failure.

    摘要: Described are photochromic organic resin compositions and the impact resistant polymerizates and coating compositions made therefrom. The organic resin composition comprises the reaction product of at least one polyol having greater than 1.0 hydroxyl groups; at least one polyisocyanate having greater than 1.0 isocyanato groups; and at least one polyamine curing agent having greater than 1.0 amino groups. The polymerizates are made photochromic either by the addition of organic photochromic compounds to the reactants used to form the polymerizate or by methods that imbibe or transfer the photochromic compounds into the polymerizate. Optically clear photochromic and impact resistant articles such as ophthalmic lenses and articles having photochromic coatings prepared from the photochromic organic resin compositions are also described.

    摘要: Liquid comprising from 93 to 100 percent by weight alcohol is removed from silica alcogel at subcritical temperature to produce silica aerogel. The silica aerogel produced by the method of the present invention not only has high porosity, but in most instances it also has a narrow distribution of small pore sizes. The silica aerogel is preferably reduced in size so as to form particulate silica aerogel.
