摘要： A composition includes a silyl hydride (having at least one silicon-bonded hydrogen atom per molecule) and a fluorinated triarylborane Lewis acid. In the method, the Lewis acid catalyzes reaction of silicon bonded hydrogen atoms from the silyl hydride and water, thereby forming a siloxane bond in the resulting product. The composition and method can be used to form siloxane intermediates and cured networks.

摘要： A process to form a crosslinked composition, the process comprising thermally treating a composition that comprises the following components: a) at least one olefin/silane interpolymer comprising at least one Si—H group, b) at least one peroxide, and c) optionally, at least one crosslinking coagent. A composition that comprises the following components: a) at least one olefin/silane interpolymer comprising at least one Si—H group, b) at least one peroxide, and c) optionally, at least one crosslinking coagent.
