| Abstract: | An acrylic acid modified rosin was prepared by the addition reaction of rosin with acrylic acid,which was further reacted with glycol,diethylene glycol or triethylene glycol to form the diacrylic acid modified rosin ester polyol.The MW,degree of polymerization,viscosity,hydroxyl value and functionality of the product were determined,and the heat resistance and IR spectrum of the product were given.It has shown that the product can be used as a heat resistant polyol component in coatings industry. |
