    摘要: A lyo gel is provided in which the gelling agent is an organic, fully synthetic polymer, which is crosslinked via its carboxylic acid groups and via metal compounds, and the swelling agent is a low-volatility, inert organic liquid having a volatility, as defined by its evaporation loss, of less than 0.5% by weight after 2 hours at 105.degree. C. in accordance with ASTM D 972. The lyo gel is useful for sealing devices involving the use of electrical current because the initially two-component reaction solution is sufficiently liquid at room temperature to fill even small spaces, such as gaps and joints between bodies.

    摘要: A plug-type connector for electrical coaxial cables includes a hot-melt-type adhesive for filling in the interior space between an outer bushing and centrally located contact bushing, with the contact bushing being configured for receiving an inner conductor of a coaxial cable. The hot-melt-type adhesive seals, fills, and insulates the interior portions of the plug-type connector surrounding the centrally located contact bushing and inner conductor of the associated coaxial cable. The hot-melt-type adhesive consists a polyamide based on dimerized fatty acids, aliphatic amines, and modifiers, and a copolyethylene and additives.
