| abstract |
The invention discloses a copolymer and a preparation method of a monomer used to form the copolymer. The copolymer is a reaction product of a first monomer and a second monomer, wherein the first monomer has a structure shown in formula (I), and the second monomer has formula (II), formula (III) Or structure shown in formula (IV) XAX? ? Formula (II) HO2CA- CO2H ? ? Formula (IV) wherein, Y is -NH 2 or -CO 2 H, m is a positive integer selected from 2-10; X is independently -NH 2 or -OH; A is n is a positive integer selected from 2-10; and l is a positive integer selected from 1-5. The copolymer of the present invention has improved physical properties. |
