Porous poly(1,8 octanediol-co-citrate) (POC) polymer networks were formed using polyethylene glycol dimethyl ether (PEGDM) as the polymer porogen. POC membranes can be made with a high degree of porosity and interconnectivity. POC membrane material can be used for drug delivery applications via pore collapse caused by a freeze-drying process. Different blending ratios of PEGDM can alter mechanical and biodegradation properties of the elastomer. The reagents used in the processing are non-toxic and show good biocompatibility in vivo.
