Beschreibung
Zusammenfassung:	The present invention relates to a catalyst system which improves the work life of acid-catalyzed resole resins at higher ambient temperatures and provides extended shelf life. The catalyst system comprises an inorganic acid catalyst and one or more polyhydric alcohols. In particular, the present invention relates to a catalyst system wherein the inorganic acid and the alcohol do not convert to anester when added to the resole resin. 本发明涉及一种催化剂体系，其改善酸催化的甲阶酚醛树脂在较高环境温度下的使用期，并且提供延长的储存期。该催化剂体系包含无机酸催化剂和一种或多种多元醇。特别地，本发明涉及一种催化剂体系，其中当加入至甲阶酚醛树脂时，无机酸和醇不转化成酯。
