Abstract
Substituted 3,4-dimethylenedioxythiophenes are provided. The substituted 3,4-dimethylenedioxythiophenes can be polymerized by chemical or electro-chemical means to produce polymers which are useful as EMI shielding and for making smart windows and switches.
Claims18
An electro-responsive polymer comprising chemically combined repeat units selected from the class consisting of, ##STR5## and a mixture thereof where R is a member selected from hydrogen or a C.sub.(1-18) organic radical.
A 3,4-dimethylenedioxythiophene having the formula, ##STR8## where R is a member selected from the class consisting of hydrogen and a C.sub.(1-18) organic radical.
A 3,4-trimethylenedioxythiophene having the formula ##STR11## where R is hydrogen and a C.sub.(1-18) organic radical.
