Abstract
A POSS-based non-isocyanate polyurethane modified poly(propylene carbonate) and a method of making are described. The POSS-based non-isocyanate polyurethane modified poly(propylene carbonate) includes a poly(propylene carbonate) and 1 to 20 wt % of a POSS-based non-isocyanate polyurethane. The method includes subjecting a POSS-based epoxy compound to a cycloaddition reaction with COto obtain a POSS-based cyclic carbonate under an action of a catalyst, and subjecting the POSS-based cyclic carbonate to a ring-opening reaction with a monoamino compound to obtain the POSS-based non-isocyanate polyurethane. Polyurethane bonds and hydroxyl in the POSS-based non-isocyanate polyurethane serve as proton donors and forms a high-density of hydrogen bonds with carbonate units of the poly(propylene carbonate), enhancing the compatibility of the POSS-based non-isocyanate polyurethane with the poly(propylene carbonate).
