Abstract: | A series of α-N,N-dihydroxyethylaminopropyl-ω-butylpolydimethylsiloxanes with different molecular weight were synthe-sized. The preparation included five steps which were hydroxyl protection, alkylation, anionic ring-opening polymerization,hydrosilylation and deprotection. The structure of reaction products was characterized by FF-IR, GC, 1H NMR. |
