  Abstract

We investigate new polyols based on castor oil for polyurethane. In order to introduce primary alcohol groups, which exhibit higher reactivity with isocyanate than secondary alcohol groups, the secondary alcohol groups on castor oil were modified with maleic anhydride and aminoalcohol derivatives (H2N-R-OH). The reactions with various molar ratio of castor oil and maleic anhydride were done at relatively low reaction temperature in the absence of catalyst. The polyols based on castor oil with flexible side-chains exhibit better miscibility with conventional synthetic polyols.
