Method for forming a graft polyol, said method comprises the steps of: a) providing a polymerizable monomer; b) provide a chain transfer agent comprising; -1) from three to nine carbon atoms, -2) at least one part of thiol, and -3) at least one hydrophilic part selected from the group of one part of hydroxyl, one part of amine and one part of carboxyl c) provide a carrier polyol; d) providing a free radical initiator comprising free radicals; e) combining the polymerizable monomer, the chain transfer agent, the carrier polyol and the free radical initiator comprising the free radicals; f) reacting the polymerizable monomer and free radicals to polymerize the polymerizable monomer and form the graft polyol. |
