A movable disc for a friction type electromagnetic clutch/brake is designed for preventing the production of grating sounds from the movable disc. The movable disc includes a rotary armature being movable in a predetermined direction by the application of electromagnetic force, a friction material stuck onto one side surface of the rotary armature, an elastic member supported on one side surface o...

A method is provided for making certain methoxy-substituted silyl benzophenones useful as ultraviolet light absorbing agents for silicone hardcoat formulations. The methoxy-substituted benzophenones have been found to more readily equilibrate into silicone hardcoat formulations without adversely affecting the shelf-life of the resulting formulation. The ultraviolet light absorbing agents are obtai...

A method of producing a porous polymeric material having open pores comprises the steps of preparing an emulsion slurry by vigorously agitating a mixture comprising a main ingredient, a polyamide hardener, a filler and water, casting said emulsion slurry in a water-impermeable mold, hardening said slurry while it contains the water. The main ingredient is a bisphenol-type epoxy resin added with on...

The invention provides polymer compositions comprising a dispersion of at least one polymer obtained by polymerisation of at least one olefinically unsaturated compound, which polymer contains aliphatic hydrocarbon side chains of at least 10 carbon atoms, in a continuous liquid phase comprising a surfactant and at least one liquid polyol; a process for the preparation of the compositions; and thei...

Nonextruded concentrates in particle form, each particle comprising: A) a matrix consisting of a nonextruded particle of an olefin polymer or copolymer, having a porosity, expressed in percentage of voids on the volume of the particle, higher than or equal to 15%; B) one or more additives, pigments or fillers, or combinations thereof, deposited on the surface of the matrix (A) and/or inside it...
