Abstract: There is provided herein a method and an apparatus for producing an isocyanatoorganosilane which method includes feeding a carbamatoorganosilane to a cracking device where it is thermally dissociated into a reaction product mixture comprising isocyanatoorganosilane, alcohol, and heavies, followed by separating the mixture in a distillation column of two parts and collecting the isocyanatoorganosilane from the distillation column via a side stream having a predetermined location between the top and bottom parts of the column; and wherein the distillation column is configured to have a ratio of the length of the bottom part of the distillation column to the length of the top part of the distillation column which is effective to provide a side stream having a high purity and high weight percent of isocyanatoorganosilane.

Abstract: A heterogeneous catalyst comprising a metal-containing polymer matrix covalently bonded to a support material and a method of making and using such catalysts. The metal-containing polymer matrix comprises metal nano-particles encapsulated in a polymer matrix, e.g., a siloxane. In one aspect, the metal-containing polymer matrix can be bonded to the support material via a hydrophobic group attached to the support material. The catalyst can be recovered after being used in a metal catalyzed reaction and exhibit excellent catalytic activity upon reuse in subsequent reactions.

Abstract: A functionalized siloxane includes a ligand capable of coordinating a metal. The functionalized siloxane includes a pyridine-containing ligand attached to a siloxane polymer. The functionalized siloxanes can be employed to provide complexes including a metal that may impart a desired property to the polymer. In one embodiment, the polymer can complex lanthanide metals that are capable of phosphorescing upon exposure to UV irradiation. Such polymers can be employed to provide functional materials such as, for example, luminescent films, coatings, etc.
