  • Process for preparing porous material having interconnected pores
    Publication number: 20040099979
    Abstract: The present invention provides a process for preparing a porous material having interconnected pores. One or more kinds of bioresorbable polymers and a low molecular weight oligomer are dissolved in an organic solvent to form a bioresorbable polymer solution. The bioresorbable polymer solution is then exposed to a coagulant to form a porous material. The low molecular weight oligomer is soluble in the coagulant, and the bioresorbable polymer is insoluble in the coagulant.
