摘要： A method of bracing an article, especially a junction between conduits subject to an internal pressure greater than that of their surroundings, which comprises applying thereto, in the order listed, a gas-impermeable member (this step may be omitted), a reinforcing member and a heat-recoverable member, the reinforcing member being radially inwardly deformable, at least at elevated temperatures, and heating the assembly to cause recovery of the heat recoverable member.

摘要： An adhesive composition comprises(a) a thermoplastic polyamide having reactive amine groups;(b) a thermoplastic copolymer of an alkene with an ethylenically unsaturated ester of an alkanol and a carboxylic acid, e.g. vinyl acetate or ethyl acrylate, and optionally one or more acidic copolymers; and(c) a thermoplastic epoxy resin.The components (a) and (b) are present in a ratio of from 35:65 to 75:25 by weight and component (c) is present in an amount of from about 8 to 79 parts per hundred parts of components (a) and (b) by weight, components (a), (b) and (c) existing separately in the form of particles that are mixed together.

摘要： Hot melt adhesives which are especially suitable for use with heat-recoverable plastics articles such as heat-shrinkable sleeves, wrap-around sleeves and end-caps are based on a combination of selected polyamides of relatively low molecular weight and relatively high amine equivalent, especially those based on dimer acids, and compatible waxes, especially low molecular weight paraffin and polyolefin waxes. The adhesive compositions advantageously comprise a tackifier, especially an aromatic tackifier, and preferred compositions include a minor amount of a rubber modifying agent to improve their low temperature flexibility and high temperature stability.
摘要翻译：特别适用于可热收缩的塑料制品如热收缩套管，环绕套筒和端盖的热熔粘合剂基于相对低分子量和相对高的胺当量的选定聚酰胺的组合，特别是那些基于二聚酸和相容的蜡，特别是低分子量的石蜡和聚烯烃蜡。粘合剂组合物有利地包含增粘剂，特别是芳族增粘剂，优选的组合物包括少量的橡胶改性剂以改善其低温柔韧性和高温稳定性。
