Abstract
The invention relates to the synthesis of polythiophene (PAT) copolymers, and their use as conductive polymers in final applications. Specifically, copolymers of PAT with (meth)acrylates, or amides are useful as additives in blends of different polymer matrices in many commercial applications.
Claims8
An electroconductive copolymer composition comprising a block copolymer having repeating segments of A and B and optionally C, in which A is selected from substituted or unsubstituted polythiophene, B comprises a methacrylic polymer, copolymer or terpolymer comprising 60 to 100 weight percent methyl methacrylate units, and C is selected from ethylenically unsaturated copolymerizable monomers other than methylmethacrylate, and wherein said block copolymer contains alkoxyamine compounds which are end-capping moieties.
