Poly(3,4-ethylenedioxythiophene)-tetramethacrylate or PEDOT-TMA is a p-type conducting polymer based on 3,4-ethylenedioxylthiophene or the EDOT monomer.

PEDOT-TMA was developed under a contract with the National Science Foundation, and it was first announced publicly on April 12, 2004.

PEDOT-TMA was featured in an article entitled "Next Stretch for Plastic Electronics" that appeared in Scientific American in 2004.

This limits the chain-length of the polymer, making it more soluble in organic solvents than PEDOT.

The chemical composition of a film of PEDOT-TMA was measured by energy-dispersive x-ray spectroscopy (EDS).
