Abstract:
(EN) The present invention addresses the problem of providing polyvinyl alcohol resin composition pellets having little coloration and improved hardness characteristics. The present invention relates to polyvinyl alcohol resin composition pellets that contain polyvinyl alcohol resin, have a hardness at 23°C and 50% RH of 100 N or higher, and have a yellow index value of 50 or lower after being heated and pressurized for two minutes at 210°C and 5 kgf/cm2.
(FR) La présente invention aborde le problème consistant à fournir des pastilles d'une composition de résine de poly(alcool vinylique) présentant une faible coloration et des caractéristiques de dureté améliorées. La présente invention concerne des pastilles d'une composition de résine de poly(alcool vinylique) qui contiennent une résine de poly(alcool vinylique), présentent une dureté à 23 °C et 50 % d'humidité relative de 100 N ou plus, et présentent un indice de jaunissement de 50 ou moins après chauffage et mise sous pression pendant deux minutes à 210 °C sous 5 kgf/cm2.
(JA) 本発明の課題は、着色が小さく且つ硬度特性を向上させたポリビニルアルコール系樹脂組成物ペレットを提供することである。本発明は、ポリビニルアルコール系樹脂を含有し、23℃、50%RHでの硬度が100N以上であり、かつ210℃、5kgf/cmで、2分間、加熱及び加圧した後のイエローインデックスの値が50以下である、ポリビニルアルコール系樹脂組成物ペレットに関する。
