- Carboxylic anhydrides are adhesives, paints, inks, toners, coating agents, molding materials, electrical insulating materials, semiconductor sealing materials, resist materials, plasticizers, lubricants, fiber treatment agents, surfactants, pharmaceuticals It is widely used as raw materials in various fields such as agricultural chemicals, resin additives or resin curing agents.
- cyclic carboxylic acid anhydrides such as tetrahydrophthalic anhydride, hexahydrophthalic anhydride, methyltetrahydrophthalic anhydride, methylhexahydrophthalic anhydride, methylnadic acid anhydride, hydrogenated methylnadic acid anhydride are epoxy resins. Since it has excellent miscibility as a curing agent and small shrinkage during resin curing, the resulting epoxy resin molded article (cured product) has excellent dimensional stability.

It is used as a sealing material for optical semiconductors (Patent Document 1 and Non-Patent Document 1).
- the cyclic carboxylic acid anhydride itself volatilizes by heating, which may lead to contamination of the heating device and significant deterioration of the working environment. It is a problem.
- the acid anhydride in the resin composition is lost in this way, there is a problem that the blending balance of the resin composition is lost and a desired cured property cannot be obtained.
- the acid anhydrides that volatilize during the heat curing of the resin have a large effect on the physical properties of the cured product, and it is difficult to obtain transparency and heat resistance of the resin.
- non-volatile acid anhydrides nonvolatile acid anhydrides
- a chain (non-cyclic) polycarboxylic acid anhydride formed by polycondensation of a polyvalent carboxylic acid has been developed.
- chain polycarboxylic anhydrides obtained by dehydration condensation reaction between aliphatic dicarboxylic acids such as polyazeline acid and polysebacic acid between molecules have been conventionally used for epoxy resins, melamine resins, acrylic powder coatings, etc. It is used as a curing agent for thermosetting resins, and when the chain polycarboxylic acid anhydride is used as a curing agent, a cured product excellent in flexibility and thermal shock resistance can be easily obtained. It is a compound useful as a curing agent for paints and casting resins (Patent Document 2).
- Patent Document 3 the following general formula (I) having at least two acyclic acid anhydrides:
- R represents a monovalent hydrocarbon group having 2 to 50 carbon atoms

- the compound specifically described in Patent Document 3 is a chain polyester compound (compound of Example 7) obtained from phthalic anhydride and 1,6-hexanediol, and this compound has an aromatic ring. Therefore, there is a problem that the cured product is easily colored, and the glass transition point (Tg), which is an index of heat resistance, is very low.

JIS C2161-B(2010年3月23日版)に従い、140℃に調節された金属板の上にエポキシ樹脂組成物の溶液を数滴垂らし、針金で組成物表面をなぞった際に、組成物と針金の間に糸を引くまでの時間(秒)を測定した。
エポキシ樹脂組成物の溶液を、アルミ箔を敷いた直径約4cmの金属製の皿に硬化後の厚みが100μmとなるように流し込み、100℃で10分間溶剤を乾燥し、130℃で2時間硬化した。この硬化物からアルミ箔を剥がして、示差熱走査熱量装置(DSC6220(SIIナノテクノロジー社製))を使用し、下記の測定条件で測定した時の変曲点をガラス転移温度(℃)とした。
ガラス転移温度の試験片と同様の方法にて作成した厚みが100μmの硬化物について、片面に上記アルミ箔を接着した状態で、分光測色計(SPECTROPHOTOMETER CM-5(コニカミノルタ(株)製)を用いて反射率を測定した。反射率からのYIの算出はASTM D1925-70(Reapproved 1988)の規定に準じて行った。硬化物を熱処理する前のYI、及び150℃で5日間熱処理した後のYIを測定し、両者の差を耐熱黄変性(ΔYI)とした。YIは硬化膜の黄色度を示し、この値が小さいほど無色透明性に優れ、値が大きくなるにつれ黄色度が増す。ΔYIは、熱履歴を受けた場合の黄変の程度、即ち耐熱黄変性を示し、この値が小さいほど硬化物の耐熱黄変性が良好である。
