20090105358	SILICONE-CONTAINING FOAMS - Foamable, isocyanate-functional organopolysiloxanes with more uniform molecular weights are produced by reaction of an aminoalkyl or hydroxyalkyl functional organopolysiloxane with a stoichiometric excess of a di- or polysiocyanate in the presence of a compatibilizer which provides a homogenous reaction mixture.	04-23-2009
20100087557	BLOWING AGENT COMPOSITION OF HYDROFLUOROPROPENE AND HYDROCHLOROFLUOROOLEFIN - A blowing agent for thermosetting foams is disclosed. The blowing agent is the hydrofluoropropene HFO-1243zf in combination with a hydrochlorofluoroolefin (HCFO) selected from HCFO-1233zd, HCFO-1233xf and HCFO-1223. The blowing agent is effective as a blowing agent in the manufacture of thermosetting foams.	04-08-2010
20110152392	Catalysts For Polyurethane Foam Polyol Premixes Containing Halogenated Olefin Blowing Agents - The invention provides polyurethane and polyisocyanurate foams and methods for the preparation thereof. More particularly, the invention relates to closed-celled, polyurethane and polyisocyanurate foams and methods for their preparation. The foams are characterized by a fine uniform cell structure and little or no foam collapse. The foams are produced with a polyol premix composition which comprises a combination of a hydrohaloolefin blowing agent, a polyol, a silicone surfactant, and a non-amine catalyst used alone or in combination with an amine catalyst.	06-23-2011
20120142795	HIERARCHICAL THERMOPLASTIC SURFACE TEXTURES FORMED BY PHASE TRANSFORMATION AND METHODS OF MAKING - Method for treating thermoplastic to make a surface thereof superhydrophobic. The method includes exposing the thermoplastic to a specific solvent for a selected time period. It is preferred that the treatment time be in the range of one minute to approximately five hours and more preferably in the range of one minute to 15 minutes. Thermoplastics and solvents having a similar solubility parameter interact with one another to form hydrophobic hierarchical surfaces.	06-07-2012
