摘要：

Poly(epsilon-caprolactone) (PCL) oligomers with -hydroxyl--alkyl end groups (alkyl=-CH2-[CH2-CH2]m-CH3, where m=1, 2, 4, 5, 6, 7, 8, 9, and 10) were synthesized by ring-opening polymerization (ROP) of epsilon-caprolactone (CL) catalyzed by ammonium decamolybdate (NH4)8[Mo10O34] and using aliphatic primary alcohols as initiators (HO-CH2-[CH2-CH2]m-CH3, where m=1, 2, 4, 5, 6, 7, 8, 9, and 10). The characterizations of the PCL oligomers were determined by MALDI-TOF, GPC, FT-IR, SAXS and 1H and 13C NMR. The effects of alkyl end groups on thermal properties of the PCL oligomers were analyzed by DSC and TGA.
