POSS® Technology is derived from a continually evolving class of compounds closely related to silicones through both composition and a shared system of nomenclature. POSS chemical technology has two unique features:
POSS molecules can be thought of as the smallest particles of silica possible. However unlike silica or modified clays, each POSS molecule contains covalently bonded reactive functionalities suitable for polymerization or grafting POSS monomers to polymer chains. Each POSS molecule contains nonreactive organic functionalities for solubility and compatibility of the POSS segments with the various polymer systems.
The chemical diversity of POSS technology is very broad and a large number of POSS monomers and polymers are currently available or undergoing development.
POSS chemical technology is easy to use with monomers available in both liquid and solid form and they are soluble in most common solvents. Hence, POSS technology can be used in the same manner as common organics, in either monomer or polymeric (resin) form. POSS chemical feedstocks can be added to nearly all polymer types (glassy, elastomeric, rubbery, semicrystalline and crystalline) and compositions.
Enhancements in the physical properties of polymers incorporating POSS segments result from POSS’s ability to control the motions of the chains while still maintaining the processability and mechanical properties of the base resin. This is a direct result of POSS’s nanoscopic size and its relationship to polymer dimensions.
