Abstract: front page image
(EN)The present invention relates to a polythiol compound, a method for preparing the polythiol compound, and a resin composition for a urethane optical material using the polythiol compound, and in particular, to a polythiol compound having extended a chain thereof through ring-opening by adding a compound having terminal thiol group to a cyclic episulfide or thietane compound, a method for preparing the polythiol compound, and a resin compound for an optical material using the polythiol compound. The optical material obtained using the polythiol compound (chemical formula 1) developed in the present invention enhances refractive index, has excellent heat resistance and reactivity, and can thus be used for optics related products including lens such as glasses lens and camera lens, prism, optical pipe, optical disk, magnetic disk, recording medium system, colored filter, infrared absorber filter, and other plastic processed products.
(FR)La présente invention concerne un composé de polyol, un procédé de préparation du composé de polyol, et une composition de résine pour un matériau optique à base d'uréthane utilisant ledit composé de polyol, et en particulier, un composé de polythiol présentant une chaîne étendue avec ouverture de cycle par ajout d'un composé présentant un groupe thiol terminal à un composé d'épisulfure ou de thiétane cyclique, et un composé de résine pour un matériau optique utilisant le composé de polythiol. Le matériau optique obtenu à l'aide du composé de polythiol (formule chimique 1) développé dans la présente invention améliore l'indice de réfraction, présente une résistance à la chaleur et une réactivité excellentes, et peut ainsi être utilisé pour des produits d'optique comprenant des lentilles tel que des verres de lunettes et des objectifs, des prismes, des conduits optiques, des disques optiques, des disques magnétiques, des systèmes de supports d'enregistrement, des filtres colorés, des filtres absorbeurs d'infrarouge, et d'autres produits de plasturgie.
(KO)본 발명은 폴리티올화합물과 그 제조 방법 및 이를 이용한 우레탄계 광학재료용 수지 조성물에 관한 것으로, 특히 고리형 에피설파이드 또는 티에탄 화합물에 말단티올기를 갖는 화합물을 첨가하여 고리개환을 통해 사슬을 연장시킨 폴리티올화합물과 그 제조 방법 및 이를 이용한 광학재료용 수지 조성물에 관한 것이다. 본 발명에서 개발한 폴리티올화합물(화학식 1)을 이용하여 얻어지는 광학재료는 굴절률을 높일 수 있고, 내열성 및 반응성이 우수하여, 안경렌즈, 카메라 렌즈 등의 렌즈, 프리즘, 광파이프, 광디스크, 자기디스크, 기록매체 기관, 착색필트, 적외선 흡수필터, 기타 플라스틱 가공품 등의 광학관련된 제품에 유용하게 사용될 수 있다.
