Attorney, Agent or FirmInternational ClassesC08J 3/00 (20060101)C08L 57/00 (20060101) AbstractA method of making and composition for a co-continuous dispersion of incompatible polymers in a polymer matrix comprises forming a solution of the incompatible polymers in a solvent which is common to both polymers and rapidly evaporating the solvent. The remaining material is in the form of the polymer matrix. | |
