Abstract: front page image
(EN)A polymer composition having an iodine number of not less than 0.1 but not more than 0.55 is obtained by adding a light stabilizer such as N,N'-bis-(2,2,6,6-tetramethyl-4-piperidinyl)- N,N'-bis-formyl-hexamethylenediamine and an antioxidant such as 2-[1-(2-hydroxy-3,5-di-t-pentylphenyl)ethyl]-4,6-di-t- pentylphenylacrylate to an alicyclic structure-containing polymer having a low iodine number. An optical molded body having an iodine number of not less than 0.1 but not more than 0.6 is obtained by molding this polymer composition containing the alicyclic structure-containing polymer and the light stabilizer and/or the antioxidant.
(FR)La présente invention concerne une composition de polymère ayant un indice d'iode non inférieur à 0,1 mais n'excédant pas 0,55 qui est obtenue en ajoutant un agent photostabilisant tel que la N,N'-bis-(2,2,6,6-tétraméthyl-4-pipéridinyl)-N,N'-bis-formyl-hexaméthylènediamine et un agent antioxydant tel que le 2-[1-(2-hydroxy-3,5-di-t-pentylphényl)éthyl]-4,6-di-t-pentylphénylacrylate à un polymère contenant une structure alicyclique ayant un faible indice d'iode. Un corps moulé optique ayant un indice d'iode non inférieur à 0,1 mais n'excédant pas 0,6 est obtenu en moulant cette composition de polymère contenant le polymère contenant une structure alicyclique et l'agent photostabilisant et/ou l'agent antioxydant.
(JA) 低ヨウ素価の脂環構造含有重合体に、N,N’-ビス-(2,2,6,6-テトラメチル-4-ピペリジニル)-N,N’-ビス-ホルミル-ヘキサメチレンジアミンなどの光安定剤と、2-[1-(2-ヒドロキシ-3,5-ジ-t-ペンチルフェニル)エチル]-4,6-ジ-t-ペンチルフェニルアクリレートなどの酸化防止剤とを添加して、ヨウ素価0.1以上0.55以下の重合体組成物を得る。そして、この脂環構造含有重合体と、光安定剤及び/又は酸化防止剤とを含有する重合体組成物を成形してヨウ素価0.1以上0.6以下の光学成形体を得る。
