摘要： Disclosed is a polyimidesiloxane adhesive made by reacting in a solution of an organic solvent a dianhydride selected from the group consisting of biphenyl dianhydride and oxydiphthalic anhydride with an approximately stoichiometric amount of a diamine. The diamine is a mixture of about 5 to about 30 mole % of a siloxane-containing diamine and about 70 to about 95 mole % of a non-siloxane containing diamine. The non-siloxane containing diamine is a mixture of about 10 to about 90 mole % each of at least two of the diamines 2,2-bis(4[4-aminophenoxy]phenyl) propane, &agr;,&agr;′-bis(4-aminophenyl)-1,4-diisopropylbenzene, 3,3′-diaminophenylsulfone, and 1,3-bis(3-aminophenoxy)benzene. The adhesive can be made into one, two, and three-layer tapes (or dispensed in other ways) which have a high Tg and a relatively low bonding temperature.

摘要： Disclosed is a resin paste made from a maleimide having at least two maleimide groups and a liquid diamine. The paste can optionally contain fillers, thickeners, defoamers, coupling agents, and solid epoxies. The resin paste has a long pot life and a short cure time and is dispensable through a syringe.
摘要翻译：公开了由具有至少两个马来酰亚胺基团的马来酰亚胺和液体二胺制成的树脂糊剂。糊料可任选地包含填料，增稠剂，消泡剂，偶联剂和固体环氧树脂。树脂糊剂具有长的适用期和短的固化时间，并且通过注射器是不必要的。

摘要： Disclosed is a solution which comprises(a) a substantially fully imidized polyimidesiloxane; and(b) a solvent which comprises at least 50 wt % of a substituted pyrrolidone having the general formula ##STR1## where R is aliphatic or cycloaliphatic from C.sub.3 to C.sub.10. Also disclosed is a method of forming a coating on a substrate by applying the solution to the substrate and evaporating the solvent. Coatings formed from this solution are not subject to whitening as are coatings formed from the same polymers in other solvents.
摘要翻译：公开了一种溶液，其包含（a）基本上完全酰亚胺化的聚酰亚胺硅氧烷; 和（b）包含至少50重量％具有通式为C 3至C 10的取代的吡咯烷酮的溶剂。还公开了通过将溶液施加到基底并蒸发溶剂来在基底上形成涂层的方法。由该溶液形成的涂层不会发生白化，因为在其它溶剂中由相同聚合物形成的涂层也不会发白。
