Improvements in molded articles which can be converted to porous carbon bodies, improvements in method for making such articles, and sacrificial binders for use in making such articles are disclosed. The sacrificial binders used in this invention comprise block polymers having the structural formulae AB-AB- eta A or X-B(AB) eta A] eta ' wherein " eta " is 0 or a positive integer, "A" is a linear or branched polymer that is glassy or crystalline at room temperature and has its softening point in the range of about 80 DEG C. to about 250 DEG C., "B" is a polymer different from "A" that behaves as an elastomer at processing temperatures, " eta '" is a positive integer greater than 2, and "X" is a linking group, a plasticizer which may be oil, wax, or oil and wax, and optionally other components. |
