摘要： Disclosed are a process for producing a tubular nonwoven fabric and tubular nonwoven fabrics produced by the same. In the process, a web is formed on a first rotating cylinder by catching fibers carried to the surface of the first rotating cylinder by a fluid, the web is transferred to a second rotating cylinder, a tube of the transferred web is formed on and around the second rotating cylinder, and the tube is drawn in the axial direction of the second rotating cylinder to form a tubular nonwoven fabric. The tubular nonwoven fabric with a high unit weight can be produced without elongating or breaking the nonwoven fabric, and the diameter of the tubular nonwoven fabric can be freely changed.

摘要： Novel silane compounds, tert.-butoxy cyclopentyl dimethoxysilane and isopropoxy cyclopentyl dimethoxysilane, are prepared by reacting cyclopentyl trihalosilane with ROH (where R stands for tert.-butyl or isopropyl group) and then with methanol, or by reacting cyclopentyl trimethoxysilane with ROH. The silane compounds are useful as a catlaytic component for olefin polymerization and as a silane coupling agent.

摘要： In a process for the preparation of epoxy group-containing alkoxy silanes by hydrosililation of a terminally unsaturated epoxy compound with a hydro-alkoxy silane using a platinum catalyst, the improvement comprising carrying out the hydrosililation in the presence of an alcohol. By this process formation of the internally sililated isomer can be suppressed and the desired terminally sililated poduct can be produced at an approximately 100% selectivity.
