Abstract: The present invention discloses POSS-based non-isocyanate polyurethane modified poly(propylene carbonate), comprising poly(propylene carbonate) and 1 to 20 wt % of POSS-based non-isocyanate polyurethane. The POSS-based non-isocyanate polyurethane has a structure shown by the formula (I) or the formula (II). Under the action of a catalyst, POSS-based epoxy compound is subjected to cycloaddition reaction with CO2 to obtain POSS-based cyclic carbonate, and then the POSS-based cyclic carbonate is subjected to ring-opening reaction with monoamino compound to prepare the POSS-based non-isocyanate polyurethane. POSS has both the flexibility of organic silicon materials and the strength of inorganic silicon materials to enhance the toughening and strengthening of of poly(propylene carbonate).
