Abstract:
In one embodiment, a block copolymer-containing composition includes PS-b-PXVP and a lithium salt, where “X” is 2 or 4. All lithium salt is present in the composition at no greater than 1 ppm by weight. In one embodiment, a homogenous block copolymer-including comprising has PS-b-PXVP present in the composition at no less than 99.99998% by weight, where “X” is 2 or 4. Methods of forming such compositions are disclosed.
