| titleOfInvention | A kind of preparation method of the amphiphilic block copolymer of poly- oxazoline polyhydroxy acid |
| abstract | The invention belongs to synthesis of polymer material field, a kind of simple process is provided, low in cost, the efficient method of reaction rate prepares the amphiphilic block copolymer of poly- oxazoline polyhydroxy acid.The present invention using the poly- oxazoline with C-terminal be macromole evocating agent 4-dimethylaminopyridine as organic catalyst, monomer of the various 'alpha '-hydroxy acids-O- carboxylic inner-acid anhydrides as ring-opening polymerisation, poly- 2- ethyl -2- oxazoline, 'alpha '-hydroxy acids-O- carboxylic inner-acid anhydride, 4-dimethylaminopyridine molar ratio be (30: 10: 1)~(100: 50: 1), at room temperature, it is used as solvent in acetonitrile, reacts 5~15min.The amphiphilic block copolymer is a kind of biocompatible materials of hydrophilelipophile, can be applied to pharmaceutical carrier, nano-reactor, film, material interface etc., while having biodegradability, is environmentally friendly material. |
