Description

本発明は、トルエン等の一般的な有機溶剤に対する溶解性が高く、かつその有機溶剤溶液を用いることによりキャスト法で容易にフィルム形状とすることができる新規の高分子化合物又は末端変性高分子化合物、及びこれらの高分子化合物とラジカル開始剤を含み、その硬化物がフレキシビリティー、耐熱性、難燃性及び接着性に優れる樹脂組成物に関する。 The present invention is a novel polymer compound or end-modified polymer compound which is highly soluble in a general organic solvent such as toluene and can be easily formed into a film shape by a casting method by using the organic solvent solution. The present invention relates to a resin composition containing these polymer compounds and a radical initiator, the cured product thereof having excellent flexibility, heat resistance, flame retardancy and adhesiveness.

芳香族ポリエステル化合物は結晶性の高い所謂液晶ポリマー樹脂と、結晶性の低い所謂非晶性ポリアリレート樹脂に大別される。
融点が270℃を超える液晶ポリマーは、熱可塑性樹脂としては極めて高い耐熱性を有することから近年フレキシブルな基板の材料に用いられている。(特許文献1)しかしながら、加工の際に融点以上の温度が必要であるためその製造設備は極めて限定されており、またその周辺部材に過剰な熱負荷が掛かることも問題であった。
一方で、液晶ポリマーよりも融点の低い非晶性ポリアリレートは、液晶ポリマーよりも低い温度で加工することができるものの、溶剤溶解性が極めて低いことが問題であった。特許文献2には溶剤溶解性を改良した非晶性ポリアリレートが記載されているが、同文献のポリアリレートは熱可塑性樹脂であるためガラス転移温度以上では流動してしまい、260℃以上の半田リフロー温度に晒される電気・電子部品用途に用い得るものではなかった。非特許文献1には、ジアリルビスフェノールAとビスフェノールAをイソフタル酸クロライドにより共重合した高分子が記載されている。この高分子化合物はアリル基を有するため光や熱ラジカル開始剤により架橋・熱硬化することが可能であるが、塩化メチレン、1,4−ジオキサン又はシクロヘキサノンといった毒性の高い溶剤にしか溶解せず、一般的なトルエンやケトン系溶剤には溶解しないことが記載されている。
Aromatic polyester compounds are roughly classified into so-called liquid crystal polymer resins having high crystallinity and so-called amorphous polyarylate resins having low crystallinity.
A liquid crystal polymer having a melting point of more than 270 ° C. has been used as a material for a flexible substrate in recent years because it has extremely high heat resistance as a thermoplastic resin. (Patent Document 1) However, since a temperature higher than the melting point is required during processing, the manufacturing equipment thereof is extremely limited, and there is also a problem that an excessive heat load is applied to the peripheral members thereof.
On the other hand, amorphous polyarylate, which has a lower melting point than the liquid crystal polymer, can be processed at a temperature lower than that of the liquid crystal polymer, but has a problem of extremely low solvent solubility. Patent Document 2 describes an amorphous polyarylate having improved solvent solubility, but since the polyarylate in the same document is a thermoplastic resin, it flows at a glass transition temperature or higher and is soldered at 260 ° C. or higher. It could not be used for electrical and electronic parts exposed to reflow temperature. Non-Patent Document 1 describes a polymer obtained by copolymerizing diallyl bisphenol A and bisphenol A with isophthalic acid chloride. Since this polymer compound has an allyl group, it can be crosslinked and thermally cured by light or a thermal radical initiator, but it is only soluble in highly toxic solvents such as methylene chloride, 1,4-dioxane or cyclohexanone. It is stated that it does not dissolve in general toluene or ketone solvents.

以下に、本発明の実施形態について説明する。
本発明の高分子化合物はジアリルビスフェノールAとジカルボン酸クロリド化合物を脱塩酸反応させることにより得ることができる。
Hereinafter, embodiments of the present invention will be described.
The polymer compound of the present invention can be obtained by dehydrochlorinating a diallyl bisphenol A and a dicarboxylic acid chloride compound.

本高分子化合物の原料であるジアリルビスフェノールAとしては市販のものが使用できる。具体的な商品名としては小西化学株式会社製のBPA−CAが挙げられる。 As the raw material of the present polymer compound, diallyl bisphenol A, a commercially available product can be used. Specific product names include BPA-CA manufactured by Konishi Chemical Industry Co., Ltd.

本発明の高分子化合物の原料であるジカルボン酸クロリド化合物の具体例としてはフタル酸ジクロリド、グルタリルクロリド、イソフタル酸ジクロリド、テレフタル酸ジクロリド、塩化オキサリル、マロニルクロリド、アジポイルクロリド、アゼラオイルクロリド、セバコイルクロリド、アゾベンゼン−4,4’−ジカルボニルジクロリド、4,4’−ビフェニルジカルボニルクロリド、イタコン酸クロリド、ヘキサハイドロテレフタル酸ジクロリド、2,6−ナフタレンジカルボン酸クロリド、4,4’−オキシジベンゾイルクロリド、2,5−フランジカルボニルジクロリド及びジグリコリルクロリド等が挙げられるが、テレフタル酸ジクロリド又はイソフタル酸ジクロリドが好ましい。 Specific examples of the dicarboxylic acid chloride compound which is the raw material of the polymer compound of the present invention include phthalic acid dichloride, glutalyl chloride, isophthalic acid dichloride, terephthalic acid dichloride, oxalyl chloride, malonyl chloride, adipoyl chloride, and azela oil chloride. , Sevacoyl chloride, azobenzene-4,4'-dicarbonyldichloride, 4,4'-biphenyldicarbonylchloride, itaconic acid chloride, hexahydroterephthalic acid dichloride, 2,6-naphthalenedicarboxylic acid chloride, 4,4'- Examples thereof include oxydibenzoyl chloride, 2,5-furandicarbonyldichloride and diglycolyl chloride, but terephthalic acid dichloride or isophthalic acid dichloride is preferable.

本発明の高分子化合物は、ジアリルビスフェノールAを有機溶剤中に均一に溶解した後に、ジカルボン酸クロリド化合物を加えて加熱下で反応させることにより合成することができる。合成の際に用いられる有機溶剤の種類としては、トルエン、キシレン、メチルイソブチルケトン、シクロペンタノン、シクロヘキサノン、N−メチルピロリドン、ジメチルホルムアミド及びジメチルアセトアミド等が挙げられ、これらの混合溶剤でも構わないが、特に沸点が低く乾燥しやすいトルエンが特に好ましい。反応温度は通常50乃至150℃であり、好ましくは60乃至140℃である。反応時間は好ましくは1乃至60時間である。 The polymer compound of the present invention can be synthesized by uniformly dissolving diallyl bisphenol A in an organic solvent, then adding a dicarboxylic acid chloride compound and reacting under heating. Examples of the type of organic solvent used in the synthesis include toluene, xylene, methyl isobutyl ketone, cyclopentanone, cyclohexanone, N-methylpyrrolidone, dimethylformamide, dimethylacetamide and the like, and a mixed solvent thereof may be used. In particular, toluene having a low boiling point and easy drying is particularly preferable. The reaction temperature is usually 50 to 150 ° C, preferably 60 to 140 ° C. The reaction time is preferably 1 to 60 hours.

反応を促進させるために触媒を使用することもできる。触媒としてはトリエチルアミン、トリプロペニルアミン及びピリジンなどの有機塩基化合物が好ましい。有機塩基化合物を触媒として使用する場合、反応によって生じる塩酸と有機塩基化合物が塩を形成するため、塩酸による反応装置の腐食を引き起こすことなく安全に反応を行うことができる。生成した塩は反応終了後、濾過によって容易に除去することができる。また反応後系中に残存する過剰の有機塩基化合物は、加熱減圧下、もしくは加熱下で窒素などのガスを系中に吹き込むことによって、溶剤と一緒に留去することができる。有機塩基化合物の使用量は発生する塩酸のモル数以上が好ましい。 A catalyst can also be used to accelerate the reaction. As the catalyst, organic base compounds such as triethylamine, tripropenylamine and pyridine are preferable. When an organic base compound is used as a catalyst, the hydrochloric acid generated by the reaction and the organic base compound form a salt, so that the reaction can be safely carried out without causing corrosion of the reaction apparatus by hydrochloric acid. The produced salt can be easily removed by filtration after the reaction is completed. Further, the excess organic base compound remaining in the system after the reaction can be distilled off together with the solvent by blowing a gas such as nitrogen into the system under heating and reduced pressure or under heating. The amount of the organic base compound used is preferably at least the number of moles of hydrochloric acid generated.

Specific examples of the polymerization inhibitor include paramethoxyphenol, methylhydroquinone, 4-t-butylpyrocatechol, t-butylhydroquinone, 1,4-benzoquinone, 6-t-butyl-2,4-xylenol, 2,6. Examples thereof include -di-t-butyl-p-cresol, 2,6-di-t-butyl-p-phenol and phenothiazine.

本発明の末端変性高分子化合物は、式(1)で表される高分子化合物の両末端が変性された化合物(即ち、式(2)中のAが−COR基の化合物)であっても一方の末端のみが変性された化合物(即ち、式(2)中のAが水素原子の化合物)であっても構わないが、両末端が編成された末端変性高分子化合物が好ましい。末端に存在するフェノール性水酸基をエステル化反応により消失させることによって、ラジカル開始剤と組み合わせた樹脂組成物(後述する)の硬化物の誘電特性が更に向上する。
The terminal-modified polymer compound represented by the formula (2) of the present invention is a compound in which the terminal of the polymer compound represented by the formula (1) of the present invention is modified with a monocarboxylic acid chloride compound, and is referred to herein. The denaturation means a dehydroxation reaction (esterification reaction) of a phenolic hydroxyl group having a terminal of a polymer compound represented by the formula (1) and a carboxylic acid chloride group of a monocarboxylic acid chloride compound.
The terminal-modified polymer compound of the present invention may be a compound in which both ends of the polymer compound represented by the formula (1) are modified (that is, a compound in which A in the formula (2) is a -COR group). A compound in which only one end is modified (that is, a compound in which A in the formula (2) is a hydrogen atom) may be used, but a terminal-modified polymer compound in which both ends are knitted is preferable. By eliminating the phenolic hydroxyl group present at the terminal by the esterification reaction, the dielectric property of the cured product of the resin composition (described later) combined with the radical initiator is further improved.

モノカルボン酸クロリド基を有する化合物としてはメタクリル酸クロリド、アクリル酸クロリド、塩化ベンゾイル、フェニル酢酸クロリドが挙げられる。 Examples of the compound having a monocarboxylic acid chloride group include methacrylic acid chloride, acrylic acid chloride, benzoyl chloride, and phenylacetic acid chloride.

モノカルボン酸ジクロリド化合物の添加量は、通常式(1)で表される高分子化合物と当モル以上であり、好ましくは式(1)で表される高分子化合物の2倍モル以上である。エステル化反応により生成した塩を濾過することにより、本発明の末端変性高分子化合物を得ることが出来る。また、反応後残存する有機塩基化合物及び未反応のモノカルボン酸ジクロリド化合物は、加熱減圧下、或いは加熱下で窒素等のガスを系中に吹きこむことにより、留去することができる。

A method of adding a compound (see above) to carry out a dehydroxylation reaction can be mentioned. A terminal-modified polymer is obtained by adding a monocarboxylic acid dichloride compound and an organic base compound to a solution obtained by a synthetic reaction of the polymer compound of the present invention. The compound may be synthesized, and the reaction conditions may be the same as those of the above-mentioned polymer compound.
The amount of the monocarboxylic acid dichloride compound added is usually equal to or more than the molar amount of the polymer compound represented by the formula (1), and preferably more than twice the molar amount of the polymer compound represented by the formula (1). The terminal-modified polymer compound of the present invention can be obtained by filtering the salt produced by the esterification reaction. Further, the organic base compound remaining after the reaction and the unreacted monocarboxylic acid dichloride compound can be distilled off by blowing a gas such as nitrogen into the system under heating and reduced pressure or under heating.

More preferably, it is 1,500 to 150,000. If the molecular weight is smaller than the above range, the film forming ability may be insufficient, and if it is large, the viscosity may be high and coating or the like may be difficult.
