Abstract
The invention relates to a process for producing a conjugated polymer blend. The process for producing the conjugated polymer blend comprises the mixture of: a polymer A (X-Y), where X is and Y is and h is a substituent, a polymer B (X-Y′) where X is Y′ is and j is a substituent, and an acceptor. In this process h and j are different substituents and independently selected from each other.
