Abstract:
A method of making a solution including a block copolymer includes dissolving the block copolymer in a solvent mixture to form a solution, the solvent mixture including at least two solvent components. The solubility of the block copolymer in the solvent mixture is at least about 7 wt. % at about 64 °C. The solvent mixture is non-reactive with the block copolymer. The solubility of the block copolymer in a single solvent solution consisting of any one of the at least two solvent components and the block copolymer is not greater than about 1 wt. % at about 64 °C. The block copolymer includes polyisobutylene segments and polyurethane segments.
