    • In one aspect, the invention provides ene-thiol elastomers comprising the reaction product of a polythiol free of hydrophilic groups and having at least two thiol groups and an aromatic, heterocyclic, aliphatic, or cycloaliphatic polyene having at least two reactive unsaturated carbon to carbon bonds. In another aspect, the invention provides ene-thiol elastomer comprising the reaction product of (a) a thiol terminated oligomer comprising the reaction product of a polythiol having two thiol groups and a first polyene or mixture of polyenes having two reactive unsaturated carbon to carbon bonds; and (b) a second polyene or a mixture of polyenes having at least 5 percent functional equivalents of unsaturated carbon to carbon bonds from polyenes having at least three unsaturated carbon to carbon bonds. The ene-thiol elastomers of the invention have a weight increase of not more than 4 weight percent in 15 days at a temperature of 22 ° C. when immersed in a solution of 96 parts by weight water and 4 parts by weight n-butanol and/or a water vapor transmission rate of less than 50 g-mm/m2-day at 40 ° C. according to ASTM D814.
    • 一方面,本发明提供了包含不含亲水基团且具有至少两个巯基的多硫醇和具有至少两个反应性不饱和碳 - 碳键的芳族,杂环,脂族或脂环族多烯的反应产物的烯 - 硫醇弹性体 。 另一方面,本发明提供了包含(a)包含具有两个硫醇基的多硫醇的反应产物和具有两个反应性不饱和碳与碳键的第一多烯或多烯混合物的硫醇封端低聚物的反应产物的烯 - 硫醇弹性体 ; 和(b)具有至少3个不饱和碳 - 碳键的多烯具有至少5%的不饱和碳与碳键的功能当量的至少5%的多烯或多烯的混合物。 本发明的烯硫醇弹性体在浸渍在96重量份水和4重量份正丁醇的溶液中时,在22℃的温度下15天内的重量增加不超过4重量%, /或根据ASTM D814在40℃下小于50g-mm / m 2·天的水蒸汽透过率。

    • A building panel for exterior and interior wall and roof surfaces comprises an elongated body formed of relatively thin, molded hardboard having upper and lower edges, opposite ends, an outer face adapted for exposure to the weather and a back face generally following the contour thereof. The body includes a lower edge portion extending upwardly and outwardly of the lower edge of the panel and integralling joining an intermediate fascia portion spaced outwardly of the lower edge. An upper edge portion integrally joins an upper edge of the intermediate fascia portion and includes an upwardly and outwardly extending segment adapted to underlie a lower edge portion of a panel(s) laid up in a next higher course. The upper edge portion also includes a second segment extending between the first segment and the upper edge of the panel and this second segment is generally parallel of the intermedate fascia panel portion and is adapted to underlie a portion of an intermediate fascia portion of a panel(s) laid up in a next higher course. The upper edge portion is formed with a plurality of longitudinally spaced apart, fastener receiving depressions extending inwardly of an outer face of the second segment of the upper edge portion. Longitudinally extending slot means are cut through the thin molded hardboard in the depressions between the inner and outer faces for receiving the shank of a nail or other fastener for securing the panels in place.
    • 用于外墙和内墙和屋顶表面的建筑面板包括由相对较薄的模制的硬纸板形成的细长主体,其具有上边缘和下边缘,相对端部,适于暴露于天气的外表面以及大体跟随其轮廓的后表面。 主体包括从板的下边缘向上和向外延伸的下边缘部分,并且将与下边缘向外间隔开的中间筋膜部分积分成一体。 上边缘部分整体地连接中间面板部分的上边缘并且包括向上和向外延伸的部分,其适合于放置在下一较高过程中的面板的下边缘部分的下面。 上边缘部分还包括在面板的第一部分和上边缘之间延伸的第二部分,并且该第二部分大致平行于中间的面板部分,并且适于在面板的中间面板部分的一部分的下面 s)放在下一个更高的课程。 上边缘部分形成有多个纵向间隔开的紧固件接收凹部,其从上边缘部分的第二段的外表面向内延伸。 在内外表面之间的凹陷处,通过薄模制的硬质板切割纵向延伸槽装置,用于接收钉子或其他紧固件的柄,用于将面板固定在适当位置。
