| titleOfInvention | Polymer molecular brush having carbon-oxa-chain structures on main chain and side chain and synthesis method thereof |
| abstract | The invention belongs to the field of the synthesis of a high molecular material, and aims to provide a polymer molecular brush having carbon -oxa-chain structures on the main chain and side chain and a synthesis method thereof. The main chain of the polymer molecular brush is a copolymer of carbon dioxide and epoxide; and the side chain is polyester, polycarbonate, polyether or a block polymer of at least two of polyester, polycarbonate and polyether. The synthesis method comprises the following steps: carrying out binary polymerization on CO2 and double-bond-containing epoxide under the catalytic action of a catalyst, or carrying out ternary polymerization on CO2, double-bond-containing epoxide and double-bond-free epoxide, thus obtaining a main chain containing lateral double bonds; carrying out double-bond-sulfhydryl reaction on the main chain containing lateral double bonds and a sulfhydryl compound, thus obtaining a main chain having lateral groups of hydroxyl and carboxyl functional groups; and obtaining a side chain according to a main-chain-grafting method or grafted-to-main-chain method. The polymer molecular brush is fully biodegradable, and can be better used as a biomedical material as compared with the molecular brush having a carbon-carbon main chain. Besides, the synthetic reaction is easy to control, and the molecular brush having a block side chain can be synthesized easily, thereby ensuring that the invention has huge application prospects in the medical high molecular material. |
