ABSTRACT:
A method for making polypyrrole structures less brittle comprising the steps of contacting the polypyrrole with an antioxidant until a desired degree of non brittleness is achieved. The antioxidants are preferably aromatic antioxidants. Polypyrroles of reduced brittleness include the antioxidants in low percentage.
