The present invention relates to tackifier compounds and methods of using the same. In various embodiments, the present invention provides a tackifier compound including independently substituted or unsubstituted fused rings A and B each independently chosen from (C5-C10)cycloalkyl and (C2-C10)heterocyclyl. Fused ring A is substituted with (R1)1-8 and fused ring B is substituted with —(OC(O)R′C(O)R2)1-8. At each occurrence R′ is independently chosen from (C2-C10)alkanylene, (C2-C10)alkenylene, (C2-C10)alkynylene, C5-C20(arylene), and (C1-C20)heteroarylene, wherein R′ is unsubstituted or substituted. At each occurrence R1 is independently selected from —OH, —OR3, and —OC(O)R′C(O)R2. At each occurrence R2 is independently chosen from —OH, —OR3, —NH2, —NHR3, and —NR32. At each occurrence R3 is independently chosen from (C1-C10)alkanyl, (C2-C10)alkenyl, (C2-C10)alkynyl, C5-C20(aryl), and (C1-C20)heteroaryl, wherein R3 is unsubstituted or substituted.
本发明涉及增粘剂化合物及其使用方法。在各种实施方案中,本发明提供了一种增粘剂化合物,包括各自独立地选自(C5-C10)环烷基和(C2-C10)杂环基的取代或未取代的熔合环 A 和 B。融合环 A 被 (R1)1-8 取代,融合环 B 被-(OC(O)R′C(O)R2)1-8 取代。在每次出现时,R′独立地选自(C2-C10)烷烃、(C2-C10)烯烃、(C2-C10)炔烃、C5-C20(芳基)和(C1-C20)杂芳基,其中 R′未被取代或被取代。在每次出现时,R1 独立选自-OH、-OR3 和-OC(O)R′C(O)R2。在每次出现时,R2 独立选自-OH、-OR3、-NH2、-NHR3 和-NR32。在每次出现时,R3 独立选自(C1-C10)烷基、(C2-C10)烯基、(C2-C10)炔基、C5-C20(芳基)和(C1-C20)杂芳基,其中 R3 是未取代的或取代的。
