Abstract

The present invention provides a polymer with new structure, its molecular structure and synthesis method have unique features. Said polymer is an amphiphilic macrocyclic polymer containing hydrophilic ring chain and oleophilic side chain. It is characterized by that said invention utilies the synthesis of a new type monomer GTEMPO containing epoxy unit to make anionic polymerization, and can introduce the functional group for regulating and controlling free radical polymerization onto cyclopolyether polymer chain to obtain cyclopolyether whose chain side has TEMOP, then utilizes active free radical polymerization to introduce the oleophilic side chain onto polyether ring, so that it can utilize ring side TEMPO to initiate styrene monomer to make controllable free radical polymerization. Said method can obtain new polymer with special structure.

Description

technical field

[0001] The invention relates to an amphiphilic macrocyclic polymer containing a hydrophilic ring chain and an lipophilic side chain and a preparation method thereof. Background technique

[0002] Since Pedersen et al. won the Nobel Prize in Chemistry in 1987 for their discovery of the cyclic ligand compound crown ether, the synthesis and application of macrocyclic ligand compounds have developed rapidly. A large number of cyclic complexes with various structures have been synthesized successively: 1) At present, the ring size of these crown ethers with lipophilic side chains is limited to 20 to 30 atoms, and most of the lipophilic chains were obtained later by chemical The reaction is connected to the nitrogen atom of the ring or the benzene ring, the number of side chains is limited, and the chemical structure of the side chains is relatively simple, and the chain length is generally within 20 atoms. 2) The use of linear polyethylene glycol (PEG) for cycliz...
