Abstract:
Processes for purifying diketopyrrolopyrrole (DPP) copolymers are disclosed. An organic phase containing the DPP copolymer is treated with an aqueous ammonia solution and then with a palladium scavenger. The DPP copolymer is then isolated, and has a very low palladium content. The resulting DPP copolymer has high mobility.
