英文摘要	to overcome the brittleness of poly(propylene carbonate) (ppc), rubbery non-isocyanate polyurethane (nipu) with rich hydrogen bonding moiety was synthesized for toughening ppc. debonding phenomenon of nipu was observed during the impact process of ppc/nipu blends, which was beneficial for toughening ppc. when the nipu loading increased to 10 wt%, the unnotched impact strength increased 3 times compared with neat ppc. the nipu dispersed uniformly and a transition from brittle to marginally tough occurred when lid reached a critical value, 1.74, where l and d were center-to-center distance and the diameter of the particle, respectively. the debonding of nipu accounted for the increase of toughness, and shear yielding of the matrix was limited around the microvoids. when the nipu loading reached 13 wt%, nipu flocculated in the matrix leading to decline in toughness. the equilibrium between self-associating hydrogen bonding and intermolecular one formed between ppc and nipu affected their miscibility and thereby the morphology of the blends.
