    • A sandwich glass is disclosed containing a thermoset resin layer interposed between glass plates, wherein the thermoset resin layer, prior to thermosetting, contains an uncured resin composition containing:(a) an organic peroxide,(b) an ethylene-vinyl acetate copolymer, and(c) at least one compound selected from the groupconsisting of at least one acryloxy or methacryloxy group-containing compound and a hydrocarbon resin having a ratio of hydrogenation .gtoreq.91%;wherein the at least one acryloxy or methacryloxy group-containing compound is selected from the group consisting of 1-methyl-1,3-dimethacryloxypropane, 2,2-dimethyl-1,3-diacryloxypropane, 2,2-dimethyl-1,3-dimethacryloxypropane, 2-hydroxy-1-acryloxy-3-methacryloxypropane, 2-hydroxy-1,3-dimethacryloxypropane, 1-hydroxy-2-methyl-1,3-diacryloxypropane and 1-hydroxy-2-methyl-1,3-dimethacryloxypropane and the ethylene-vinyl acetate copolymer contains vinyl acetate in an amount of 10-50% by weight. The sandwich glass of the present invention results in an improved resistance to yellowing and less perspective distortion.
    • 公开了一种夹层玻璃,其包含介于玻璃板之间的热固性树脂层,其中热固性树脂层在热固化之前含有未固化的树脂组合物,其包含:(a)有机过氧化物,(b)乙烯 - 乙酸乙烯酯共聚物和 (c)至少一种选自至少一种含丙烯酰氧基或含甲基丙烯酰氧基的化合物和氢化比例> 91%的烃树脂的化合物; 其中所述至少一种含丙烯酰氧基或含甲基丙烯酰氧基的化合物选自1-甲基-1,3-二甲基丙烯酰氧基丙烷,2,2-二甲基-1,3-二丙烯酰氧基丙烷,2,2-二甲基-1,3 二羟甲基丙烯酰氧基丙烷,2-羟基-1-丙烯酰氧基-3-甲基丙烯酰氧基丙烷,2-羟基-1,3-二甲基丙烯酰氧基丙烷,1-羟基-2-甲基-1,3-二丙烯酰氧基丙烷和1-羟基-2-甲基-1,3 二丙烯酰氧基丙烷和乙烯 - 乙酸乙烯酯共聚物含有10-50重量%的乙酸乙烯酯。 本发明的夹芯玻璃导致改善的耐黄变性和较少的透视变形。
