Abstract

Polylactones blended with a polyether and then shaped are leached with aqueous solution of an organic solvent such as alcohol or acetone to elute selectively the polyether and form interconnected pores within the shaped polylactone. The result is a shaped article suitable for use a reservoir for the controlled release of high molecular weight drugs.
