Abstract
A graft polyol includes a natural oil including at least 50% by weight of a natural oil polyol. Particles are dispersed in the natural oil and comprise the reaction product of a macromer polyol, a polymerizable monomer, a chain transfer agent, and a free radical initiator. The macromer polyol and the polymerizable monomer react in the presence of the natural oil. The graft polyol is formed by providing the natural oil and providing the macromer polyol, the chain transfer agent, the free radical initiator, and the polymerizable monomer. The natural oil, the polymerizable monomer, the macromer polyol, the chain transfer agent, and the free radical initiator are combined, and the polymerizable monomer, the macromer polyol, the chain transfer agent, and the free radical initiator react to form particles dispersed in the natural oil.
