1. A phase-separated polymeric composition comprising:
i. a first phase including polyurethane domains; and ii. a second phase including a butyl rubber matrix, wherein the polyurethane includes mer units deriving from a phenolic resin and mer units deriving from a diisocyanate, wherein said polyurethane domains are discrete domains within said butyl rubber matrix at a temperature of up to about 80° C. and the polyurethane domains have a mean particle diameter of less than 10 μm, and wherein the polyurethane domains are bonded to the butyl rubber through a phenolic resin couple. |
