Abstract
A water soluble polymer blend composition includes at least one water soluble polymer and at least one immiscible polymer. The water soluble polymer and the immiscible polymer can be melt processed at a temperature above their respective melt processing temperatures and quenched to form the water soluble polymer blend composition in a non-equilibrium state, such that it can exhibit a non-equilibrium morphology. Non-equilibrium morphologies can include, e.g., a microfiber morphology or a co-continuous morphology.
Claims15
A water soluble polymer blend composition comprising:
- at least one water soluble polymer;
- and
- at least one immiscible polymer;
- wherein the at least one water soluble polymer and the at least one immiscible polymer are processed above the respective melt processing temperatures of the at least one water soluble polymer and the at least one immiscible polymer and quenched to form the water soluble polymer blend composition;
- wherein the water soluble polymer blend composition has a nonequilibrium morphology;
- and
- wherein the non-equilibrium morphology of the water soluble polymer blend composition is a microfiber morphology.
