Embodiment example 1
[0024] (1) Take 50g of fully dried polyethylene glycol monomethyl ether 500 and 30g of NAD and mix them, place them in an autoclave, and add 5g of catalyst. The catalyst contains 65% by weight of cobalt, 32% by weight of aluminum and 0.5% by weight. % Copper, heated to 200°C, reacted for 15 hours at a pressure of 0.8 MPa to obtain a yellow liquid, centrifuged at a speed of 10,000 rpm for 15 minutes, and took the supernatant to proceed to the next step.
[0025] (2) In the supernatant, add 300ml of tetrahydrofuran, then add 18g of γ-benzyl-L-glutamate-N-lactam acid anhydride and 20g of catalyst, the catalyst contains 30wt% The hydrogen bromide was stirred at 25°C for 72 hours. After the reaction, the product was settled with ether, washed repeatedly, filtered, and dried in vacuum to obtain the amino acid-polyether-polyester copolymer.
Embodiment example 2
[0027] (1) Take 50g of fully dried polyethylene glycol monomethyl ether 500 and 35g of NADP and mix them, place them in an autoclave, and add 10g of catalyst, which contains 95wt% cobalt, 3wt% aluminum and 0.3wt% % Copper, heated to 200°C, reacted for 10 hours at a pressure of 1.2 MPa to obtain a yellow liquid, centrifuged at a speed of 10,000 rpm for 15 minutes, and took the supernatant to proceed to the next step.
[0028] (2) In the supernatant, add 500ml of tetrahydrofuran, then add 25g of γ-propynyl-L-glutamate-N-lactam acid anhydride and 35g of catalyst, the catalyst contains 20wt% The palladium on carbon was stirred at 30°C for 55 hours. After the reaction, the product was settled with ether, washed repeatedly, filtered, and dried in vacuum to obtain the amino acid-polyether-polyester copolymer.
[0029] In the structure of polyamino acid-coenzyme-polyether copolymer, it is a highly branched tree structure, and the side chain contains a large number of structures connected b...
