| 中文摘要 | poly(propylene carbonate) (ppc), a biodegradable plastic produced by alternating copolymerization of carbon dioxide and propylene oxide, is amorphous at glass-transition temperature of similar to 35 degrees c; therefore, it becomes brittle at temperatures <20 degrees c. this article reports on the synthesis of low molecular weight urethanes, such as 1,6-bis(hydroxyethyl urethane)hexane (beu), 1,6-bis(hydroxyisopropyl urethane) hexane (bpu), and 1,6-bis(methyl urethane)hexane (hdu) bearing rich nh and c=o bonds, by a non-isocyannate method and their use as plasticizers for ppc. the hydrogen-bonding interaction between bpu and ppc was found to be significantly more effective as compared with beu and hdu, and the highest hydrogen-bonding interaction fraction reached 5.2% in a ppc/bpu blend with 15 wt% bpu loading. solubility parameters calculated from hoy's method, in combination with differential scanning calorimetric analysis, indicated that hdu and bpu were miscible with ppc at a molecular scale, while beu was immiscible with ppc. usually, plasticizing is generally accompanied by sacrificing of tensile strength; however, it was encouraging to observe that the elongation at break for ppc/hdu blend with 10 wt% of hdu loading reached 727% - an increase 53 times that of pure ppc - while the tensile strength was maintained at 30 mpa, which was comparable with that of linear low-density polyethylene. the hydrogen-bonding interaction generated a remarkable improvement in the mechanical performance of ppc; it not only confined the migration of the plasticizer to the surface and thus ensured stability of the blending material over time, but it also maintained the mechanical strength of the plasticized ppc.
