Claim 0:
1. A supramolecular star-shaped polymer with β-CD as a core, having a β-cyclodextrin-modified branched monomer F-β-CD that serves as a core and is grafted with acrylamide, acrylic acid, hydrophobic monomers and surface-active macromolecular monomers to form the supramolecular star-shaped polymer;
wherein said β-cyclodextrin-modified branched monomer F-β-CD has the following structure:, in said supramolecular star-shaped polymer with β-CD as a core, its branch chain has the following structural formula:, where, x, y, m and n are a percentage of a structural unit, x is 70-85%, y is 10-25%, m is 0.05-0.2%, n=1-x-y-m; A is the hydrophobic monomer, which is one or more of N-benzyl-N alkyl (meth) acrylamide and N-phenethyl-N alkyl (meth) acrylamide; B is the surface-active macromolecular monomer, which is one or more of allyl polyoxyethylene ether, alkyl phenol polyoxyethylene ether (methyl) acrylate, alkyl phenol polyoxyethylene ether allyl ether, alkyl alcohol polyoxyethylene ether (meth)acrylate and alkyl alcohol polyoxyethylene ether allyl ether; said supramolecular star-shaped polymer with β-CD as a core has a viscosity-average molecular weight of 1 to 8 million.
