This invention relates to a process for the preparation of improved terpene-phenol resins particularly useful in the field of adhesives, comprising: A. reacting 1 molar proportion of a phenol having at least 2 reactive sites with 0.4-0.6 molar proportion of a carene, in the presence of an acidic condensation catalyst; B. reacting the reaction product obtained in step (a) with 0.4-0.6 molar proportion of said carene in the presence of said catalyst, and C. subsequently reacting the material obtained in step (b) with a reactive terpene, the molar ratio between said reactive terpene and the amount of carene added in step (b) being comprised between 0.5 and 5.
本发明涉及一种制备改进的萜烯-酚树脂的方法,特别适用于粘合剂领域,包括:A.在酸性缩合催化剂的存在下,将至少具有2个反应位点的酚的1个摩尔比例与0.4-0.6摩尔比例的萜烯反应;B.在该催化剂的存在下,将步骤(a)中得到的反应产物与0.4-0.6摩尔比例的萜烯反应;C.随后将步骤(b)中得到的物质与反应性萜烯反应,所述反应性萜烯的摩尔比与步骤(b)中添加的萜烯的量之比在0.5至5之间。
