| titleOfInvention | Preparation method of high-refractive-index PU (polyurethane) modified polysiloxane |
| abstract | The invention discloses a preparation method of high-refractive-index PU modified polysiloxane, which comprises the steps of mixing aromatic diisocyanate, a catalyst A, a stabilizer and a polymerization inhibitor with a sulfur-containing heterocyclic monomer, heating to react under the condition of introducing inert gas, adding a catalyst B and hydroxyl-terminated polysiloxane for heating to react, adding a terminating agent for reacting, adding water for stirring, and separating to obtain the high-refractive-index PU modified polysiloxane. The method is an improved synthetic route, can obviously improve the stability of the sulfur-containing heterocyclic groups in the synthetic process, ensures that the prepared resin has small smell and good compatibility with organic silicon resin and polyurethane, and has mild preparation conditions and simple process. |
