以下、下記実施例により本発明をさらに詳細に説明する。但し、下記実施例は、本発明を例示するためのものであるのみ、本発明の範囲がこれらのみに限定されるものではない。
[重合性組成物の調製]
ポリチオール化合物として、第1ポリチオール化合物(ポリチオール化合物2番)56重量部と、第2ポリチオール化合物(ポリチオール化合物9番)56重量部とを混合した後、1,3-ビス(イソシアナトメチル)シクロヘキサン(イソシアネート化合物2番)109.8重量部を添加して均一に混合した。これに、重合触媒としてジブチルスズジクロリド0.01重量部、内部離型剤としてZelec(登録商標)UNを0.1重量部、および紫外線安定剤Seesorb(登録商標)709を0.2重量部で添加し、均一に混合して重合性組成物を調製した。
前記重合性組成物を600Paで1時間脱気した後、3μmのテフロンフィルターでろ過した。ろ過された重合性組成物を、テープで組み立てられたガラスモールドに注入した。前記モールドを25℃から120℃まで5℃/分の速度で昇温させ、120℃にて18時間重合させた。その後、ガラスモールドで硬化された樹脂を130℃にて4時間さらに硬化した後、ガラスモールドから成形体(プラスチックレンズ)を離型させた。
下記表3に記載のように、ポリチオール化合物およびイソシアネート化合物の種類および/または重量比を変化させたことを除いては、参考例1の方法と同様に行ってプラスチックレンズを製造した。
前記調製された重合性組成物を対象に、下記記載の通りにして物性を測定し、測定結果を下記表4に示した。
参考例1、実施例2~5および比較例1~3で製造されたプラスチックレンズについて、動的機械分析装置(DMA-Q800)を使用して、4℃/分、1Hzで動的機械熱分析(Dynamic Mechanical Thermal Analysis)を行い、25℃における貯蔵モジュラス(E'(@25℃))と、70℃における貯蔵モジュラス(E'(@70℃))およびtanδと得た。前記結果値について、常温(25℃)での貯蔵モジュラス/70℃における貯蔵モジュラスの比(E'(@25℃)/E'(@70℃))と、下記数学式1による常温(25℃)におけるエネルギー減衰(KEL)を計算した。
KEL(エネルギー減衰)=tanδ×1012/[E'(@25℃)×(1+(tanδ)2)]
参考例1、実施例2~5および比較例1~3で製造されたプラスチックレンズについて、TMA-Q400(TA Instruments社)を用いて、ペネトレーション法(50g荷重、ピン先0.5mmΦ、昇温速度10℃/分)でガラス転移温度(Tg)を測定した。
参考例1、実施例2~5および比較例1~3で製造されたプラスチックレンズを固定させた後、127cmの高さから16gの鉄球(steel ball)を落下させて、レンズの割れ、亀裂などの破損有無を観察した。レンズ面のひび割れや、レンズが割れる場合はFail、割れずに表面状態が良好であればPassと評価した。
参考例1、実施例2~5および比較例1~3で製造された成形体を、ISO75に基づく基準数値(長さ×幅×厚さ=80mm×10mm×4mm)でそれぞれ5個作製し、熱変形試験機(HDT:Heat Deflection Temperature、HD-PC、安田精機製作所)を用いて、平均90℃以上にて変形が起こるサンプルはPass、平均90℃以下にて変形が起こるサンプルはFailと評価した。
