| titleOfInvention | Dendritic polymer and synthesis method and application thereof |
| abstract | The invention belongs to the technical field of dendritic polymer, and particularly relates to a dendritic polymer and a synthesis method and application thereof. The invention takes 4- (vinyl phenyl) -1-butylene as a repeating unit to construct a chain segment at the periphery of a polymer; using sec-butyl lithium to initiate VSt polymerization reaction; under the action of Karstedt's catalyst, the double bond and dimethyl chlorosilane produce hydrosilylation reaction to produce high activity grafting site capable of producing coupling reaction with several kinds of active anionic chain to prepare the multicomponent dendritic polymer. In addition, the number of grafting sites can be controlled by regulating the polymerization degree of the PVSt chain segment, and the dendritic polymer with high grafting density can be prepared. The dendritic polymers have wide application prospect in the aspect of reducing the processing viscosity of the polymers. In addition, G4-P2VP is dissolved in trifluoroacetic acid aqueous solution, and pyridine groups in molecules of the G4-P2VP have strong coordination capability, so that the G4-P2VP has wide application prospect in the aspect of polymer micelles. |
