Disclosed is an implant device comprising a polymeric material comprising a release agent, wherein: the polymeric material further comprises the polymerization product of at least two ethylenically unsaturated monomers the device is a molded, reservoir implant and the release agent is a non-ionic surfactant having a molecular weight of at least 1000 gram per mol. Further disclosed for preparing said device, comprising: charging a polymerization column or a mold with at least two ethylenically unsaturated monomers and a release agent and rotating the polymerization column or mold about its longitudinal axis at a speed sufficient to displace the monomer radially outward along the interior surfaces of the polymerization column or mold maintaining the polymerization column or mold at a position substantially parallel to the ground polymerizing the at least two ethylenically unsaturated monomers and recovering a reservoir implant device wherein the release agent has a molecular weight of at least 1000 gram per mol. Also disclosed is an implant device when prepared by said process.
