It is also used in the transesterification reaction.[1] Application Dibutyltin dilaurate is used as a catalyst in: - The synthesis of polyurethane (PU) and polyhydroxyurethane (PHU) prepolymers and lignin urethane.[2] [3] - A protocol for the covalent attachment of poly(ethylene glycol) (PEG) to silicon oxide to form a hydrophilic non-fouling surface.[4] - Preparation of polymers by reacting hydroxyl-terminated macromonomers and aliphatic diisocyanates.[5][6][7][8] |
