Method of forming a graft polyol and polyurethane article formed from the graft polyol.

摘要

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