    • A thermosetting aqueous-type emulsion of nadimide is disclosed. The emulsion comprises 1-70% by weight of an alkenyl-substituted nadimide, 0.1-20% by weight of protective colloid and/or surface-active agent and balance water. The emulsion is especially useful for making a paint, a coating material or an adhesive because the emulsion can easily be cured only by heating without forming any undesirable organic pollutants. In the past, various resins have been used together with organic solvents. However, because of the recent worldwide concern over the influence of organic solvents to pollution of the aerospace and underground environments, non-use or reduced-use of organic solvents is actively desired. Accordingly, developments of aqueous solution or aqueous-type emulsion of resins are desired. Until now there is no aqueous-type emulsion of a monomer of highly heat resistant polyimide.
    • 公开了一种纳米二酰亚胺的热固性水性乳液。 乳液包含1-70重量%的链烯基取代的酰亚胺,0.1-20重量%的保护胶体和/或表面活性剂和余量的水。 该乳液特别可用于制备涂料,涂料或粘合剂,因为乳液可以容易地通过加热固化而不形成任何不期望的有机污染物。 以往,各种树脂与有机溶剂一起使用。 然而,由于最近全球对有机溶剂对航空航天和地下环境污染的影响令人担忧,因此积极地期望不使用或减少有机溶剂。 因此,需要开发树脂的水溶液或水性乳液。 到目前为止,还没有高耐热聚酰亚胺单体的水性乳液。

    • A resist polymer solution comprising a resist polymer containing a repeating unit decomposed by the action of an acid so as to be soluble in alkali and a repeating unit having a polar group, the resist polymer dissolved in a solvent for coating film formation, wherein the amount of impurities whose boiling point is not higher than that of the solvent for coating film formation is 1 mass % or less based on the resist polymer. Further, there is provided a process for producing a resist polymer solution, comprising the step (1) of redissolving a solid matter containing a resist polymer in a solvent for coating film formation (a) and/or a solvent (b) whose boiling point at atmospheric pressure is not higher than that of the solvent (a); and the impurity removing step (2) of distilling off the solvent (b) and/or any excess amount of solvent (a) in vacuum from the redissolution solution obtained in the step (1).
