    摘要: 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 R′ 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.

    摘要: A method of making an amino acid triisocyanate is provided, the method comprising reacting an amino acid trihydrochloride with phosgene to form the amino acid triisocyanate. In some embodiments, the amino acid trihydrochloride comprises lysine ester trihydrochloride salt and the amino acid triisocyanate comprises lysine ester triisocyanate. In some embodiments, there is a lysine ester triisocyanate having a purity of at least about 98%, the lysine ester triisocyanate having a structure resulting from reacting lysine ester trihydrochloride salt with phosgene to form the lysine ester triisocyanate. These lysine ester triisocyanates can be used to make biodegradable polyurethanes.

    摘要: Water-triggered shape memory polymers based on poly(ε-caprolactone) (PCL) and poly(ethylene glycol) (PEG) multiblock hybrid thermoplastic polyurethanes. Urethane linkages were formed through the addition reaction between isocyanate groups of the lysine methyl-ester diisocyanate (LDI) and the hydroxyl groups of either (PEG) or PCL diol.
