Microporous polymer matrices |
| abstract |
A method for the manufacture of a microporous polymer matrix comprises the steps of: a) introducing into a mould a solution of polymer in a solvent, and b) adding a precipitant to the solution so as to cause precipitation of the polymer from the solution in a form which retains the shape of the mould upon removal from the mould. Useful polymers for carrying out the method of the invention are those which show a tendency to crystallise from solution on solvent extraction. These include poly(L.lactide) or copolymers of poly(L.lactide) and a poly (α-hydroxy acid) which will dissolve in acetone and subsequently crystallise upon solvent extraction. The preferred polymer is poly(ε-caprolactone). The precipitant is preferably a solvent in which the polymer is substantially insoluble. Preferred precipitants are polar solvents such as alcohols, in particular methanol. |
