摘要： An electrical connector assembly for interconnecting a pair of circuit boards in parallel spaced-apart planes comprises first and second connectors. The first connector includes a dielectric first housing having a mating face and an array of first contacts exposed along the mating face. The first housing has a shroud which defines a boundary around the array of first contacts. The shroud has an edge at a height above the mating face and the first contacts are recessed below the edge. The second connector includes a dielectric second housing having a mating face and an array of second contacts exposed along the mating face for mating with the first contacts. The second housing is configured for complementary reception within the boundary of the shroud, wherein the shroud serves to align the first and second housings for mating before engagement of the first and second contacts can occur.

摘要： Various polymeric compositions, including bicomponent networks and multiblock copolymers, containing polyisobutylene are synthesized by linking a plurality of polyisobutylene polymer chains with siloxane compounds having at least two SiH moieties. Specifically, bicomponent networks are synthesized by linking multifunctional polyisobutylenes, preferably tri-telechelic allyl-terminated polyisobutylenes, with multifunctional linear polysiloxanes, such as di-telechelic linear SiH-terminated polydimethylsiloxane, by hydrosilation. Similarly, multiblock copolymers are synthesized by endlinking difunctional allyl-terminated polyisobutylenes with difunctional SiH-terminated linear polysiloxanes, such as polydimethylsiloxanes, by hydrosilation. Still other polymeric networks comprising polyisobutylene are synthesized by linking multifunctional polyisobutylenes, preferably di- or tri-telechelic allyl-terminated polyisobutylenes, with multifuntional SiH-containing compounds, preferably cyclosiloxanes such as hexamethylhexahydrocyclosiloxane, by hydrosilation.

摘要翻译： 通过将多个聚异丁烯聚合物链与具有至少两个SiH部分的硅氧烷化合物连接来合成包含聚异丁烯的各种聚合物组合物，包括双组分网络和多嵌段共聚物。 具体地说，双组分网络通过将多官能聚异丁烯，优选三末端烯丙基封端的聚异丁烯与多官能线性聚硅氧烷（例如通过硅氢化硅烷二脱氧线性SiH封端的聚二甲基硅氧烷）连接来合成。 类似地，多嵌段共聚物通过通过硅氢化作用将双功能烯丙基封端的聚异丁烯与双功能SiH封端的直链聚硅氧烷如聚二甲基硅氧烷端接而合成。 还包括聚异丁烯的其它聚合物网络通过将多官能聚异丁烯，优选二取代或三末端烯丙基封端的聚异丁烯与通过硅氢化硅烷化合物的多官能SiH化合物，优选环硅氧烷如六甲基六氢环硅氧烷连接而合成。
