This invention discloses a method for preparing functionalized polyolefins, belonging to the field of polymer modification technology. The method includes the following steps: homogenizing a polyolefin, a grafting monomer, and a high-valent iodine compound, followed by heating to obtain the functionalized polyolefin; wherein the grafting monomer is selected from at least one of N-hydroxyphthalimide and its derivatives, and N-hydroxysuccinimide and its derivatives. This method uses a high-valent iodine compound as an initiator, which preferentially activates the polyolefin molecular chain and forms a pre-bonded complex with the grafting monomer. This significantly inhibits the non-selective β-fracture degradation and inter-chain crosslinking of the polyolefin backbone caused by free radicals, maintains the stability of the base molecular weight, and achieves efficient grafting of the grafting monomer.

The present application relates to the technical field of CT enhanced imaging hydrogel, and particularly relates to a CT enhanced imaging hydrogel, a preparation method and application thereof. The CT enhanced imaging hydrogel is obtained by in-situ cross-linking reaction of a hydrogel framework and an iodine-substituted cross-linking agent. The hydrogel framework comprises a multi-arm polyethylene glycol derivative. The amino compound is modified by an iodine-containing compound, and then condensed by an amino-carboxyl condensing agent to obtain the iodine-substituted cross-linking agent, which can introduce iodine atoms with a wider density range, and has a low influence on the cross-linking reaction of the amino group of the multi-arm polyethylene glycol derivative and the iodine-substituted cross-linking agent. The obtained hydrogel has obvious imaging advantages and safety.
