Title (EN) POLYURETHANE/THIOURETHANE-BASED OPTICAL RESIN AND PROCESS FOR PRODUCING THE SAME
(FR) RÉSINE OPTIQUE À BASE DE POLYURÉTHANE/THIOURÉTHANE ET SON PROCÉDÉ DE PRODUCTION
(JA) ポリウレタン・チオウレタン系光学用樹脂およびその製造方法
Abstract: front page image
(EN)A process in which a polyurethane/thiourethane resin can be produced from a polyisocyanate compound, a polyol compound, and a polythiol compound without causing abrupt heat generation or viscosity increase. At least one polyol compound having one or more ether bonds and two or more hydroxy groups per molecule is used as the polyol compound, whereby large heat generation and an abrupt viscosity increase are inhibited from occurring upon monomer mixing.
(FR)La présente invention concerne un procédé selon lequel une résine de polyuréthane/thiouréthane peut être produite à partir d'un composé polyisocyanate, d'un composé polyol et d'un composé polythiol sans entraîner de réaction exothermique brusque ou sans augmentation brusque de la viscosité. Au moins un composé polyol ayant une ou plusieurs liaisons éther et deux ou plusieurs groupes hydroxy par molécule est utilisé en tant que composé polyol, moyennant quoi on empêche l’occurrence d’une réaction très exothermique et d’une augmentation brusque de la viscosité lors du mélange des monomères.
(JA) ポリイソシアナート化合物とポリオール化合物とポリチオール化合物とを用いてポリウレタン・チオウレタン系樹脂を製造する場合に、急激な発熱や粘度上昇を伴わず、操作できる方法を提供する。ポリオール化合物として、1分子中に1個以上のエーテル結合と2個以上のヒドロキシ基を有するポリオール化合物の少なくとも1種を使用することにより、モノマーを調合時の大きな発熱や急激な粘度上昇が抑制される。
