用于对亲核剂敏感之可交联组成物的以脂肪酸二醯胺爲主之添加剂;ADDITIVES BASED ON FATTY DIAMIDES FOR CROSSLINKABLE COMPOSITIONS WHICH ARE SENSITIVE TO NUCLEOPHILES

摘要

本发明系有关于一以脂肪酸二醯胺为主的组成物，其包含且尤其由以下所组成：a)自92至100重量%之一或多种脂肪酸二醯胺，其系于原位经一中和剂处理以使残留胺含量减至一残留胺值(其系以毫克KOH/克表示)，其残留量小于0.5，b)可择地，至高8重量%之至少一具有大于60℃之Tg的非晶形或半结晶状寡聚物，且该a)+b)之重量%的总合等于该二醯胺组成物之100重量%，且a)及b)系可混溶成一掺合物。;本发明亦涵盖一用于制备该以二醯胺为主的组成物之方法。本发明之该以二醯胺为主的组成物系作为用于含对亲核官能基敏感之组份(诸如胺)(其系作为反应性组份)之可交联组成物以防止过早交联的流变添加剂。这些组成物系有关于涂覆物、黏着剂、胶泥、密封剂或模制组成物。;The invention also covers a process for the preparation of the said diamide-based composition. The diamide-based composition of the invention is used as rheology additive in crosslinkable compositions comprising, as reactive component, a component which is sensitive to nucleophilic functional groups, such as amine, preventing them from prematurely crosslinking. These compositions relate to coatings, adhesives, mastics, leaktightness agents or moulding compositions.
