摘要：A method of producing a delivery device for delivering a chemical compoundincludes i) providing an interpenetrating polymer substrate (IP substrate) having a firstcontinuous polymer comprising rubber and a second polymer having hydrogel or ahydrogelable precursor, where the second polymer is interpenetrating in the firstpolymer; ii) providing the chemical compound and a loading solvent for the chemicalcompound; and iii) loading the IP substrate with the chemical compound by subjecting theIP substrate to the loading solvent having the chemical compound under conditionswhere the loading solvent at least partially swells the second polymer. The chemicalcompound, the second polymer and the loading solvent are selected such that the workof adhesion (Whc) between the second polymer and the chemical compound during atleast a part of the loading is at least about 0 J/m2.
