A particular class of sulfolanyloxyalkyl-polyalkylsiloxanes are provided which consists essentially of: (1) monofunctional siloxy units (M DEG ) the respective silicon atoms of which have two alkyls bonded thereto, the third silicon-bonded organic group being alkyl or sulfolanyloxyalky; (2) an average of from about 0.5 to about 10 moles of difunctional dialkylsiloxy units for every two moles of M ...

PURPOSE:A bead molded article having improved shock-absorbing properties, high mechanical strength, and low permanent set, obtained by subjecting a polypropylene resin to expansion molding in such a way that the molded article has a specific crystallization latent heat, density, and number of foams. CONSTITUTION:Pre-expanded particles are fed to a mold which can be closed but not hermetically seal...

A nonwoven fabric comprising hydrophobic polyester fibers bonded with a water-insoluble, hydrophobic emulsion polymer of 50 to 95 parts by weight of a C1 to C2 alkyl acrylate; 5 to 30 parts of an ethylenically unsaturated monomer selected from styrene, methyl methacrylate, and alpha -methyl styrene; and 0.1 to 5 parts of a monoethylenically unsaturated carboxylic acid containing 3 to 6 carbon ato...

The present invention provides for a novel fiber-reinforced cement-like material which is characterized by having short polyvinyl alcohol fibers in an amount of at least 2 volume % based on the total volume of said material. These fibers have an elongation at break of between about 4 and 8% and a modulus of more than 130 g/dtex. A process for the preparation of said material is also disclosed.

PURPOSE:To keep the distance between a head and a disc plane constant even if the speed changes, by providing a pressure reducing skew groove branching main stream to a down stream region of air flow, for an opposing plane of a disc plate of a slider main body. CONSTITUTION:When a disc surface turns, th air flow guided with the viscous friction is compressed through the guiding operation of a tilt...

In a paging storage subsystem, a plurality of addressable data storage devices (16-18) are selectively directly accessed using direct addresses (21, 26) or accessed via a cache memory (100), using one of a plurality of logical addresses (23, 25), each of the data storage devices being represented by a plurylity of the logical addresses. Each of the data storage devices can be reserved for direct a...

The invention relates to a process for the synthesis of 1,1'-diacetals, which method is also suitable for the stereoselective synthesis of glycosides with the 1,1'-diacetal structure. The process involves reacting a silyl compound of formula (II) with an acetal of formula (III) in the presence of a catalyst of formula (IV) or (V) in a suitable solvent.
