硬化性組成物調製の具体的態様は、ポリイソ(チオ)シアネート化合物と含水率が5000ppm以下の硬化触媒とを混合して混合物を調製する工程(以下、「工程1」とも記載する。)と、調製した混合物とポリチオール化合物とを混合する工程(以下、「工程2」とも記載する。)と、を含む。好ましくは、ポリイソ(チオ)シアネート化合物を、ポリチオール化合物と混合する前に上記硬化触媒と混合する。即ち、上記混合物は、ポリチオール化合物を含まないことが好ましい。ここで「含まない」とは、積極的に添加しないことを意味し、不純物として意図せず混入することは許容されるものとする。ポリイソ(チオ)シアネート化合物をポリチオール化合物と混合する前に硬化触媒と混合することは、光学的な歪の少ない硬化物を得るうえで好ましい。ただし本発明者らは、ポリイソ(チオ)シアネート化合物を、ポリチオール化合物と混合する前に硬化触媒と混合すると、含水率が5000ppm以下の硬化触媒を用いなければ、硬化反応により得られる硬化物において脈理および白濁が顕著に発生する傾向があると考えている。詳しくは、次の通りである。
ポリイソ(チオ)シアネート化合物が有するイソ(チオ)シアネート基は、チオール基と反応することにより先に示した結合を形成するが、水とも反応し得る。例えば、イソシアネート基(-NCO)は、水と反応することにより-NHCOOHに転換され、-NHCOOHが脱炭酸すると-NH2となる。即ち、水との反応によりアミンが生成される。更にこのアミンとイソシアネート基が反応することによりウレア結合が形成される。即ちウレア化合物が生成される。同様の反応は、イソチオシアネート基についても起こり得る。本発明者らは、こうして生成されるアミン等が脈理発生の一因であり、ウレア化合物等が白濁発生の一因と考えている。詳しくは、アミン等が硬化反応の反応速度(重合速度)に影響を及ぼすことが脈理発生の一因と考えている。また、ウレア化合物等が硬化性組成物に含まれるポリイソ(チオ)シアネート化合物およびポリチオール化合物に対する溶解性に乏しいことが、白濁発生の一因と考えている。ただし一方で、イソ(チオ)シアネート化合物は、ポリチオール化合物が有するチオール基と高い反応性を有する。そのため、ポリイソ(チオ)シアネート化合物とポリチオール化合物とを含む反応系に水が含まれていた場合、イソ(チオ)シアネート基はチオール基と主に反応すると考えられる。したがって、イソ(チオ)シアネート基と水との反応に起因するアミン等およびウレア化合物等によって引き起こされる脈理および白濁は、ポリチオール化合物を含まない反応系と比べて発生し難いと推察される。これに対し、ポリイソ(チオ)シアネート化合物を、ポリチオール化合物と混合する前に硬化触媒と混合すると、硬化触媒に含まれる水分の影響が顕在化する結果、硬化反応により得られる硬化物において脈理および白濁が顕著に発生すると考えられる。これに対し、本発明の一態様にかかる硬化物の製造方法によれば、硬化触媒として含水率が5000ppm以下の硬化触媒を用いることで、硬化物における脈理および白濁の発生を抑制することができる。
上記硬化性組成物におけるポリチオール化合物とポリイソ(チオ)シアネート化合物との混合割合は、特に限定されないが、例えば、モル比として、ポリチオール化合物に含まれるチオール基/ポリイソ(チオ)シアネート化合物に含まれるイソ(チオ)シアネート基=0.5~3.0の範囲、好ましくは0.8~1.4、更に好ましくは0.9~1.1の範囲とすることができる。混合割合を上記範囲とすることは、高屈折率、高耐熱性等の各種優れた物性を有する硬化物を提供可能な硬化性組成物を得るうえで好ましい。一方、上記硬化触媒量は、硬化性化合物の全量に対して、例えば10~10,000ppmであることができ、50~8,000ppmであることが好ましい。なおここに記載の「ppm」は、質量基準である。また、上記の具体的態様では、工程1において上記硬化触媒を、ポリイソ(チオ)シアネート化合物100質量部に対して、例えば0.005~10質量部の量でポリイソ(チオ)シアネート化合物と混合することができる。なお硬化触媒としては、一種または二種以上の硬化触媒を用いることができる。二種以上の硬化触媒を用いる場合の硬化触媒量は、それら二種以上の硬化触媒の合計含有量をいうものとする。本発明および本明細書において、特記しない限り、異なる構造を取り得る成分は一種用いてもよく二種以上を用いてもよい。かかる成分を二種以上用いる場合の含有量は、二種以上の合計含有量をいうものとする。
以上説明した硬化性組成物調製工程において調製された硬化性組成物を硬化することにより、硬化物として、眼鏡レンズ等の光学部材の材料として有用なポリチオウレタン系樹脂を得ることができる。硬化触媒として含水率が5000ppm以下の硬化触媒を用いることにより、硬化反応により得られる硬化物における脈理および白濁の発生を抑制することが可能となる。
実施例、比較例において硬化性組成物を調製するために用いる硬化触媒の含水率を、温度20~25℃および絶対湿度2~5g/m3以下の環境下で、カールフィッシャー水分測定装置(京都電子工業株式会社製自動水分測定装置MKC-610型)を用いて測定した。実施例で用いた硬化触媒は、真空脱気を行い含水率を低減させた硬化触媒である。
