Abstract
The present application provides a modified resin, a preparation method therefor and a composition thereof. The preparation method comprises: reacting a polymer polyol, an acrylic acid compound and an acid anhydride compound, to obtain a prepolymer, a structural formula of the prepolymer containing a double bond; reacting the prepolymer with an epoxy resin under the action of a catalyst, to obtain a modified resin. The modified resin prepared in the present application introduces a polymer polyol segment and an acrylic acid segment to the structural formula thereof, and the introduction of long flexible segments can improve the flexibility of a cured film; in addition, by means of introducing an acid anhydride compound segment to the structural formula of the modified resin, as the introduction of a rigid structure can improve the heat resistance of a modified resin, it is possible to adapt to higher temperature application scenarios.
