- 3. The polyaldehyde of claim 1, which is prepared by reacting glyoxal with tetra(amidoethyoxy) tetramethyl methane.
- 4. The polyaldehyde of claim 1, wherein the polyester is triethyl citrate, dimethyl adipate, or dimethyl glutarate.
- 5. The polyaldehyde of claim 1, wherein the molecular weight of the polyaldehyde is about 250-1000.
