Abstract
This invention discloses a novel process to prepare multi-block copolymers with high molecular weights from two immiscible polymer segments. In one embodiment, the two polymer segments are reacted in a solvent mixture which comprises N-methyl-2-pyrrolidinone and diglyme. Such polymers are useful for alignment layer applications in display devices.
