An uncured elastomer/porogen mixture comprising an elastomer and a porogen composition for coating a biocompatible implantable device, the porogen composition comprising a core material and a shell material, wherein the core material comprises at least two compounds, wherein the shell material has a melting temperature that is lower than a melting temperature of the core material, and wherein the shell material is adjacent to the core material, and the elastomer is selected from a group consisting of:
- bromo isobutylene isoprene (BIIR), polybutadiene (BR), chloro isobutylene isoprene (CIIR), polychloroprene (CR), chlorosulphonated polyethylene (CSM), ethylene propylene (EP), ethylene propylene diene monomer (EPDM), fluorinated hydrocarbon (FKM), fluoro silicone (FVQM), hydrogenated nitrile butadiene (HNBR), polyisoprene (IR), isobutylene isoprene butyl (IIR), methyl vinyl silicone (MVQ), acrylonitrile butadiene (NBR), polyurethane (PU), styrene butadiene (SBR), styrene ethylene/butylene styrene (SEBS), and acrylonitrile butadiene carboxy monomer (XNBR).
An uncured elastomer/porogen mixture comprising an elastomer and a porogen composition for coating a biocompatible implantable device, the porogen composition comprising a core material and a shell material, wherein the core material comprises at least two compounds, wherein under a given physical or physicochemical treatment the shell material transitions from a solid phase to a liquid phase and the core material remains in a solid phase, and wherein the shell material is adjacent to the core material, and the elastomer is selected from a group consisting of:
- bromo isobutylene isoprene (BIIR), polybutadiene (BR), chloro isobutylene isoprene (CIIR), polychloroprene (CR), chlorosulphonated polyethylene (CSM), ethylene propylene (EP), ethylene propylene diene monomer (EPDM), fluorinated hydrocarbon (FKM), fluoro silicone (FVQM), hydrogenated nitrile butadiene (HNBR), polyisoprene (IR), isobutylene isoprene butyl (IIR), methyl vinyl silicone (MVQ), acrylonitrile butadiene (NBR), polyurethane (PU), styrene butadiene (SBR), styrene ethylene/butylene styrene (SEBS), and acrylonitrile butadiene carboxy monomer (XNBR).
