Description
【0001】
【発明の属する技術分野】
本発明は、ポリウレタン用樹脂原料、塗料原料、(チオ)エポキシ樹脂硬化剤、合成樹脂の加硫剤等の各種原料や添加剤への用途および、含硫(メタ)アクリル化合物、含硫エポキシ化合物、含硫エピスルフィド化合物等の各種含硫化合物の原料等として有用なポリチオールに関し、特にプラスチックレンズ用モノマーとして好適なポリチオール並びにそれを使用した重合性組成物、およびそれを重合させてなる光学樹脂、その樹脂よりなるプラスチックレンズに関するものである。
【0002】
【従来の技術】
チオウレタン系プラスチックレンズは、その強靭な性質と優れた光学物性によって、眼鏡用プラスチックレンズ用途で、現在広く普及している。中でも、2,5−ビス(メルカプトメチル)−1,4−ジチアンを用いたウレタン系プラスチックレンズ(特公平7−5585号公報、特公平6−5323号公報)はその他のポリチオールを用いたウレタン系プラスチックレンズの場合よりも、耐熱性が優れているという特徴を有している。
【0003】
【発明が解決しようとする課題】
しかしながら、この2,5−ビス(メルカプトメチル)−1,4−ジチアンを用いても、例えば、キシリレンジイソシアナートに代表されるような高屈折率を与えるポリイソシアナートと重合させたとしても、屈折率がまだ不十分であった。
【0004】
【課題を解決するための手段】
本発明者らは、上述の課題を解決するために、鋭意検討した結果、下記式(I)
【0005】
【化2】
で表される新規なポリチオールを創製し、該化合物を使用すれば、2,5−ビス(メルカプトメチル)−1,4−ジチアンを使用した場合よりもさらに屈折率が向上することを見出し、本発明に到達した。
【0006】
即ち、本発明は、
1)前記式(I)で表されるポリチオール。

Solvents used for hydrolysis include water, alcohols such as methanol, ethanol, isopropanol, and butanol, aromatic hydrocarbon solvents such as toluene and xylene, and halogenated hydrocarbon solvents such as dichloromethane, dichloroethane, and chlorobenzene. Preferably used.
[0035]
If the isothiuronium chlorination reaction of the previous step is performed with water and alcohols, and hydrolysis is performed without taking out the reactants, hydrolysis is performed in a two-layer system by adding aromatic hydrocarbon solvents such as toluene and xylene. It is relatively preferable to perform the cleaning operation because the cleaning operation performed thereafter may be performed efficiently and in a short time.
[0036]
The reaction solution containing the formula (I) relating to the present invention thus obtained is usually subjected to various washings such as pickling, base washing, and water washing as necessary, and after removing the solvent, the product is obtained by filtration. . Moreover, it refine | purifies by the well-known purification methods used normally, such as distillation and column chromatography.
[0037]
The polythiol according to the present invention thus obtained is not only used as a monomer for optical resins, particularly as a monomer for plastic lenses, but also as a raw material for polyurethane resins, paint raw materials, epoxy curing agents, synthetic resin vulcanizing agents, It can be suitably used for a wide variety of uses such as raw materials for various sulfur-containing compounds such as sulfur-containing (meth) acrylic compounds, sulfur-containing epoxy compounds, and sulfur-containing episulfide compounds.

Next, the production of the plastic lens according to the present invention will be described.
The polythiol represented by the formula (I) according to the present invention is a compound having a group that reacts with a mercapto group, for example, a polyiso (thio) cyanate, a (thio) epoxy group, a compound having an unsaturated group, and added if necessary. After mixing with an agent or the like uniformly and defoaming by stirring under reduced pressure or the like, a defoaming solution is injected into the molding mold and cured mainly by heating or radiation to obtain the plastic lens of the present invention.
[0039]
As heating conditions, the temperature is gradually raised from a low temperature to a high temperature in a temperature range of about 0 ° C. to 200 ° C., and is finished in about 1 hour to 100 hours.
[0040]
When polymerizing by radiation, ultraviolet rays of 400 nm or less are often used. The ultraviolet irradiation conditions are often from 1 to 7200 seconds with an intensity of about 1 mJ / sec to 1000 mJ / sec. Sometimes, for the purpose of removing heat or obtaining an optically uniform molded product, it is cooled before irradiation. In some cases, irradiation is performed while cooling, or irradiation is performed in several steps.

A 500 ml reaction flask was charged with 109.3 g (0.72 mol) of 2-mercaptomethyl-1,3-dithiolane, 2.9 g (35.7 mmol) of 49% aqueous sodium hydroxide and 200 ml of methanol, and at 10 ° C., epichlorohydrin. 69.0 g (0.75 mol) was added dropwise over 2 hours. After completion of dropping, the mixture was aged at 10 ° C. for 1 hour. The reaction mass was concentrated under reduced pressure to obtain 180.6 g of crude 2- (1-chloro-2-hydroxy-3-thiabutyl) -1,3-dithiolane. Subsequently, 200 ml of toluene was charged, and 128.0 g (1.08 mol) of thionyl chloride was added dropwise at 75 ° C. over 1 hour. After completion of dropping, the mixture was aged at 70 ° C. for 2 hours. The reaction mass was concentrated under reduced pressure to obtain 217.9 g of crude 2- (1,2-dichloro-3-thiabutyl) -1,3-dithiolane. Subsequently, 163.8 g (2.15 mol) of thiourea, 3.6 g (35.9 mmol) of 98% sulfuric acid and 200 ml of ethanol were charged and aged at 75 ° C. for 11 hours. After completion of aging, 300 ml of toluene and 229.2 g (3.23 mol) of 24% aqueous ammonia were added dropwise at 20 ° C. over 30 minutes. After completion of dropping, the mixture was aged at 60 ° C. for 5 hours. After completion of ripening, the solution was neutralized and separated with 336.5 g (3.23 mol) of 35% aqueous hydrochloric acid, washed with water, desolvated, and the target compound 2- (1-mercapto-2-mercaptomethyl). There was obtained 41.1 g (0.16 mol) of -3-thiabutyl) -1,3-dithiolane.

Example 2 Production of plastic lens
Compound synthesized according to Example 1 {2- (1-mercapto-2-mercaptomethyl-3-thiabutyl) -1,3-dithiolane} 13.7 g (0.053 mol), 4- (mercaptomethyl)- 3,6-dithiaoctane-1,8-dithiol 13.8 g (0.053 mol), xylylene diisocyanate 24.9 g (0.132 mol), dibutyltin dichloride 10.4 mg (200 ppm) as a curing catalyst, UV absorber 2- (2-hydroxy-5-t-octylphenyl) benzotriazole 26.2 mg (500 ppm), internal mold release agent di (1- (1- (1-n-butoxy-2-propoxy) -2-propoxy) 2-propyl) phosphoric acid 78.6 mg (1500 ppm) was mixed and defoamed while being uniformly mixed and dissolved under reduced pressure. It was cast into a mold consisting of a lath mold and a gasket.
Subsequently, it was cured by heating over 20 hours while gradually raising the temperature from 40 ° C to 130 ° C. After the polymerization was completed, the mixture was gradually cooled and the polymer was taken out from the mold.
[0074]
The obtained thiourethane plastic lens was transparent and had a refractive index of 1.670, an Abbe number of 32, and heat resistance of 95 ° C. The results are listed in Table 1.
