摘要： Thermally crosslinked polysulfone may be made from linear polysulfone, such as polyethersulfone, in powder form blended with a powdered inorganic peroxide such as magnesium peroxide or another oxygen source, to form a mixture followed by compression inside a mold. The mixture is cured at a an elevated temperature, for instance above 325° C., for an effective period of time to form a dense object. The object is then boiled in water, optionally under pressure, to remove the salt to give a structure that is open and porous which may be used as a filtration device on a downhole tool for hydrocarbon recovery. If a powdered salt is not used, a thermally crosslinked, solid, void-free polysulfone is made which may be strong and rigid at ambient, surface temperatures, but is an elastomer at elevated downhole temperatures, and is thus suitable for use as a packer or an O-ring.
摘要翻译：热交联聚砜可以由直链聚砜（例如聚醚砜）制成，粉末形式与粉状无机过氧化物如过氧化镁或其它氧源混合，以形成混合物，随后在模具内压缩。混合物在升高的温度（例如高于325℃）下固化一段有效的时间以形成稠密的物体。然后将物体任选在压力下在水中煮沸以除去盐，得到开放和多孔的结构，其可用作井下工具用于烃回收的过滤装置。如果不使用粉末盐，则制成热交联，无固体，无空隙的聚砜，其在环境温度下可能是强的和刚性的，但是在升高的井下温度下是弹性体，因此适合用作封隔器或O形圈。
