    摘要: A polymerizable, liquid, substantially gel-free composition comprising a partially polymerized mixture of ethylenically unsaturated compounds wherein: (a) the mixture of ethylenically unsaturated compounds which was partially polymerized comprised a mixture of diethylene glycol (allyl carbonate) compounds each represented by Formula (I) or by Formula (II), in which n is a positive integer, m is a positive integer, and the diethylene glycol (allyl carbonate) compound for which the value of n is 1 constituted from 25 to 75 area percent of the mixture of diethylene glycol (allyl carbonate) compounds; and (b) the ethylenic double bond utilization of the polymerizable, liquid, substantially gel-free composition is at least 3 percent. The polymerizable, liquid, substantially gel-free composition exhibits low shrinkage in the mold when polymerized.

    摘要: A polymeric material comprising main chain ether groups or side chain alkoxylated groups that is effective as a carrier of photochromic additives. The polymeric material preferably has a glass trnsition temperature of at least 125 DEG F and a cross link density of 2 to 8 moles per liter, more preferably 2.5 to 6 moles per liter. When photochromic additives are incorporated in such materials, the speed of switching is maintained at a high level, while the level of photochromic response is rendered relatively insensitive to temperature changes. Examples of optical products into which such materials can be incorporated include ophthalmic lenses, goggles, safety glasses, windows, and windshields.

    摘要: Organic resin compositions of from about 30 to 90 weight percent of a polyol(allyl carbonate), e.g., diethylene glycol bis(allyl carbonate), and from about 10 to 70, e.g., 10 to 30, weight percent of a mixture of aliphatic urethanes, the terminal portions of which contain allyl or acrylyl functional groups. Polymerizable compositions prepared from such compositions produce castings which have low yellowness (b*) values and which do not pre-release from the molds in which they are formed. Polymerizates prepared from such compositions may be used to prepare photochromic articles, e.g., lenses, by incorporating a photochromic substance, e.g., by thermal transfer, into the polymerizate.

    摘要: A polymerizable liquid composition includes

    a polymerizable poly(allyl carbonate) of an aliphatic or cyclo-aliphatic polyol;
    an organic peroxide generator of free radicals selected from the group of perketals, and possibly
    an organic dye and/or an organic photochromic compound.

    The compositions can be transformed, by bulk polymerization, into an organic glass which is colourless, or coloured or photochromic, having good optical and mechanical characteristics.
