Title (EN) UV CURABLE ACRYLIC POLYMER AND METHOD FOR PRODUCING SAME, AND UV CURABLE HOT MELT ADHESIVE
(FR) POLYMÈRE ACRYLIQUE DURCISSABLE AUX UV, SON PROCÉDÉ DE FABRICATION, ET ADHÉSIF THERMOFUSIBLE DURCISSABLE AUX UV
(JA) 紫外線硬化型アクリル系ポリマー及びその製造方法並びに紫外線硬化型ホットメルト接着剤
Abstract:
(EN) The present invention provides a UV curable acrylic polymer which can be used as a UV curable hot melt adhesive that exhibits excellent heat stability and coatability when melted, without requiring a stabilizer and that achieves desired adhesiveness by being cured by UV irradiation. The UV curable acrylic polymer according to the present invention crosslinks by UV irradiation, and is characterized in that, after being heated at 150ºC for 6 hours, the rate of change of the weight average molecular expressed in terms of standard polystyrene weight is -20% to 20%.
(FR) La présente invention concerne un polymère acrylique durcissable aux UV qui peut être utilisé comme adhésif thermofusible durcissable aux UV présentant une excellente stabilité à la chaleur et au revêtement en fusion, sans nécessiter de stabilisant et permettant d'obtenir une adhésivité souhaitée en étant durci par un rayonnement UV. Le polymère acrylique durcissable aux UV selon la présente invention se réticule par irradiation UV, et est caractérisé en ce que, après chauffage à 150 °C pendant 6 heures, le taux de changement du poids moléculaire moyen exprimé en termes de poids de polystyrène étalon est de -20 % à 20 %.
(JA) 本発明は、安定剤の必要とすることなく、溶融時の熱安定性及び塗工性に優れ且つ紫外線照射による硬化によって所望の粘着性を発現する紫外線硬化型ホットメルト粘着剤として使用可能な紫外線硬化型アクリル系ポリマーを提供する。本発明の紫外線硬化型アクリル系ポリマーは、紫外線の照射によって架橋する紫外線硬化型アクリル系ポリマーであって、150℃にて6時間加熱された後の標準ポリスチレンにより換算された重量平均分子量の変化率が-20~20%であることを特徴とする。
