    摘要： A process for the manufacture of a partially cured polysulphide composition is provided, the curing of which is completed upon exposure of the composition to atmospheric moisture. The process comprises mixing a prepolymer with a water activatable curing agent and subjecting the composition to a partial cure with water. The reaction is then stopped by rapid dehydration after the initial induction stage of the reaction prior to the rapid increase in the viscosity of the composition. Curing of the composition is then completed by exposing the composition to atmospheric moisture.

    摘要： An insulated glass unit comprises two sheets of glass separated by an aluminum spacer, a thermosetting resin sealant such as a polysulphide or polyurethane sealant or a hot melt butyl sealant being applied around the edges of the unit to seal the sheets together. The spacer is connected by corner keys made of aluminum tape. Curing or melt-bonding of the sealant is accelerated by the application of microwave energy, suitably by passing the unit through a tunnel with microwave generators on each side thereof. The unit passes through the tunnel on a conveyor held upright by pinch chains. The conveyor and pinch chains are made of a nonpolar material such as polypropylene.

    摘要： Polysulfide sheeting is prepared by mixing a curable polysulfide oligomer or polymer, carbon black, and manganese dioxide as a hardening catalyst; forming the composition into a sheet; and curing the sheet at an elevated temperature. The sheeting has unusually high short-term heat resistance, so it will not lose its watertightness when coated with hot-laid asphalt at 240.degree. C. It has better resistance to ultraviolet light than conventional polysulfide sheeting, and good penetration and compression set resistance. The sheeting can be laminated to a reinforcing layer, if desired. A continuous waterproofing layer can be formed by laying pieces of the sheeting in overlapping relation, placing an uncured polysulfide rope between the overlapping edges of adjacent pieces of sheeting, and curing the rope, thus joining the pieces to form an integral sheet. Such waterproof layers can be incorporated into paving for bridges, roofs, and other structures.

    摘要翻译： 通过混合可固化多硫化物低聚物或聚合物，炭黑和二氧化锰作为硬化催化剂制备多硫化物薄片; 将组合物形成片材; 并在升高的温度下固化片材。 片材具有非常高的短期耐热性，因此在240℃下涂布热敷沥青时不会失去其防水性。它比常规多硫化物薄膜具有更好的抗紫外线能力，以及良好的穿透和抗压缩变形性。 如果需要，片材可以层压到加强层上。 连续防水层可以通过以相互重叠的方式铺设片材而形成，将未固化的多硫绳放置在相邻的片材的重叠边缘之间，并固化绳索，从而连接件以形成整体的片材。 这种防水层可以结合到桥梁，屋顶和其他结构的铺路中。
