| titleOfInvention | Preparation method of hyperbranched organic-inorganic block optical transparent addition type organic silicon material |
| abstract | The invention relates to the technical field of organic silicon, and aims to solve the problem of poor mechanical property of an organic silicon high polymer material, the invention provides a preparation method of a hyperbranched organic-inorganic block optical transparent addition type organic silicon material, wherein hydroxyl-terminated aliphatic hyperbranched polyester is reacted with metal organic lithium under the protection of nitrogen, and then n-hexane is used for cleaning for a plurality of times to prepare a hyperbranched macroinitiator; then in the presence of an accelerator, ring-opening polymerization is carried out on the hyperbranched macroinitiator and a cyclic organosilicon monomer, the reaction is terminated by a terminator, so as to obtain a hyperbranched block organosilicon macromolecule, and the solvent, the low molecule and the monomer which does not participate in the polymerization reaction are removed under reduced pressure; then, obtaining the hyperbranched organic-inorganic block optical transparent addition type organosilicon material through hydrosilylation reaction. Improves the mechanical property and the flow property of the organic silicon polymer material. |
