Title (EN) NOVOLAC RESIN AND METHOD FOR PRODUCING SAME
(FR) RÉSINE NOVOLAQUE ET PROCÉDÉ DE PRÉPARATION ASSOCIÉ
(JA) ノボラック樹脂およびその製造方法
Abstract:
(EN) Disclosed is a method for producing a novolac resin, wherein a phenol and an aldehyde are reacted with each other in the presence of a catalyst that contains calcium chloride and an acid.  The method is characterized in that a novolac resin having a low molecular weight and a low melt viscosity is efficiently produced by reacting a phenol and an aldehyde with each other under mild conditions.
(FR) La présente invention concerne un procédé de préparation d'une résine novolaque de bas poids moléculaire et de faible viscosité à l'état fondu qui consiste à faire réagir un phénol et un aldéhyde dans des conditions douces en présence d'un catalyseur qui contient du chlorure de calcium et d'un acide.
(JA)  塩化カルシウムおよび酸を含む触媒の存在下、フェノール類とアルデヒド類とを反応させるノボラック樹脂の製造方法であって、フェノール類とアルデヒド類とを温和な条件下で反応させて、溶融粘度が低く、低分子量のノボラック樹脂を効率的に製造する方法を提供する。
