| 发明名称 | Block copolymer-comprising compositions and methods of purifying PS-<i>b</i>-PXVP | ||
| 摘要 | 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. | ||
