摘要 Polyols are basically compounds containing multiple reactive hydroxyl groups and one of the major constituting elements in making polyurethane and polyurethane foam. Traditionally, the polyols are obtained from fossil fuels. The limited availability of fossil fuels and exponentially increasing demand of polymers including PUs enforce the scientific society to explore the possible alternate sources for obtaining polyols. In order to reduce the dependency of polyols on fossil fuels, renewable polyols have gained significant importance over the last few decades. Various biomass and renewable sources have been explored to obtain the polyols. The present review, which is a continuation of our earlier work, highlights various other starting raw materials of plant origin for obtaining the renewable polyols and corresponding methodologies. The review also attempts to make a strong connection between the starting material for making polyols, chemical transformations employed, and the properties of polyols as well as final PUs. The comprehensive analysis of renewable polyols and corresponding PUs will help researchers in making commercially viable renewable polyols to fulfill the increasing demand.
