Ester polymer, preparation method therefor and use thereof

Abstract:

An ester polymer has a structure represented by the following formula (I): ##STR00001## T represents the backbone of the ester polymer; the group B is each independently selected from O or S; the group R each independently represents C.sub.1-10 hydrocarbylene group; the group A is each independently selected from O, S or NR''; the group R' each independently represents C.sub.1-10 hydrocarbylene group; the group N.sub.b is each independently selected from H or --R'''--B'H, wherein at least one of the two N.sub.b on the same nitrogen atom is --R'''--B'H; the group R'' is each independently selected from H or C.sub.1-10 hydrocarbyl group; the group R''' each independently represents C.sub.1-10 hydrocarbylene group; the group B' is each independently selected from O or S; each y independently represents an integer between 1 and 6; and m is an integer between 1 and 10.
