Patent ID: 8124720

Claim:
A degradable polymer prepared by: reacting a triazine-based monomeric compound with a monomer or a prepolymer which is capable of reacting with the triazine-based monomeric compound by condensation or addition polymerization, wherein the triazine-based monomeric compound is represented by the following formula (I): wherein E is H or a substituted triazine group represented by the following formula: and D 1 is represented by the following formula: -G 1 -B—X-G 2 - wherein B is selected from the group consisting of 1,3-cyclohexylene, 1,4-cyclohexylene, meta-phenylene, para-phenylene, and a divalent heterocyclic group; wherein, when B is 1,3-cyclohexylene, 1,4-cyclohexylene, meta-phenylene, or para-phenylene and X is a hydrocarbylene group or a single bond, G 1 and G 2 are independently N or O; and wherein, when B is a divalent heterocyclic group and X is a hydrocarbylene group or a single bond, G 1 and G 2 are independently N, O, or a single bond, in which, when one of G 1 and G 2 is a single bond, an atom of said heterocyclic ring bonding to said single bond is a hetero-atom, and in which, when G 2 is a single bond, X is a single bond, and when E is H, B is a 1,4-piperazinylene group, 1,4-piperidylene group or wherein each of A 1 and A 2 is independently a substituent group, and at least one of A 1 and A 2 is an active hydrogen-containing group for condensation or addition reaction; and wherein each of A 1 ′, and A 2 ′, is independently a substituent group, and at least one of A 1 ′, and A 2 ′, is an active hydrogen-containing group for condensation or addition reaction.
