Abstract: This invention provides novel azlactone-functional oligomers of 2-alkenyl azlactones in which oligomerization has occurred predominantly via the 2-alkenyl group. Oligomerization of the 2-alkenyl group provides oligomers having 2 to 15 mer units with predominantly carbon-carbon backbone segments. Oligomerized in this fashion, the novel compositions possess azlactone groups which can be reacted with nucleophiles in the normal ring-opening sense. The oligomers are prepared by a novel process in which both Lewis and Bronsted acidic catalysts are effective. The reactive oligomers find utility as crosslinking agents for polymers containing azlactone-reactable nucleophilic groups.

Abstract translation: 本发明提供2-链烯基吖内酯的新型吖内酯官能低聚物，其中低聚主要通过2-链烯基发生。 2-烯基的低聚提供了具有主要为碳 - 碳骨架链段的2至15个mer单元的低聚物。 以这种方式低聚，新型组合物具有吖内酯基团，其可以以正常的开环方式与亲核试剂反应。 低聚物通过其中Lewis和Bronsted酸性催化剂都有效的新方法制备。 反应性低聚物可用作用于含有吖内酯可反应的亲核基团的聚合物的交联剂。
