Abstract

An ester polymer has a structure represented by the following formula (I): 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 C1-10 hydrocarbylene group; the group A is each independently selected from O, S or NR″; the group R′ each independently represents C1-10 hydrocarbylene group; the group Nb is each independently selected from H or —R″′—B′H, wherein at least one of the two Nb on the same nitrogen atom is —R″′—B′H; the group R″ is each independently selected from H or C1-10 hydrocarbyl group; the group R″′ each independently represents C1-10 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.
