摘要:
Process for the preparation of a hydroperoxide functionalized olefinic compound in an oxidation reactor containing a particulate catalyst bed comprising a light induced photosensitized catalyst component supported on a particulate substrate material forming a permeable catalyst bed. The photoenergized catalyst component is a photoreductant material which is effective for the conversion of triplet oxygen to singlet oxygen under illumination with ultraviolet or visible light. An oxygen containing feed stream containing triplet oxygen is supplied to the catalyst bed. The catalyst bed is irradiated at an intensity to convert triplet oxygen to singlet oxygen to produce a singlet oxygen enriched gas stream. The enriched gas stream is supplied to a second reactor which contains a dispersion of an olefinic component having an allylic hydrogen which is contacted with the enriched gas stream under conditions effective to cause an allylic rearrangement and introduce hydroperoxide functionalization into the olefinic component.

An exit alarm system housed in an escutcheon for activating upon movement of an interior latch operator. The system is mounted to the interior side of a door with a latch assembly including an interior latch operator. The system may include an alarm, a trigger, and an electronic module. The trigger is responsive to movement of the interior latch operator. The electronic module may be electrically connected to a power source for providing an input signal to the alarm. Upon motion of the interior latch operator, the trigger may cause the electronic module to send an activating input signal to the alarm. The alarm may be a sound transducer. A switch may be provide to arm the system. A tamper switch may be provided to cause the electronic module to activate the alarm upon removal of the escutcheon. The system may be applied to retrofit an existing door.
摘要:
Polyolefins may be prepared using a cocatalyst conforming to the formula: AIRz(Xz)nLzm wherein Rz is a linear or branched organic moiety having at least 5 carbons and Xz is a linear or branched organic moiety having at least 5 carbons or a heterocyclic moiety having at least 4 atoms and can be anionic or di-anionic. The aluminum complex may also be in the form of an adduct complex where Lz is a Lewis base and m=1-3. The cocatalyst Rz components are selected such that they do not react with water under polymerization conditions to form a species that is highly soluble in the polymerization diluent. Use of the specified cocatalyst reduces fouling during metallocene-catalyzed runs and “post-metallocene hangover” when the same production equipment is transitioned to non-metallocene catalyst runs using catalysts such as chromium.
摘要:
A method of forming a polyolefin catalyst component includes halogenating metal complexes. The metal complexes result from reacting a metal alkoxide with an alcohol-ether. A particular non-limiting example is a magnesium complex formed by reacting magnesium alkoxide with an ethylene alcohol-ether, and then chlorinating the magnesium complex. Catalyst components, catalysts, catalyst systems, polyolefin polymers and methods of making each are disclosed.
摘要:
It has been discovered that the amount of fluoropolymer additive used in a polyethylene resin affects the quality of finish of an article made with free surface polyethylene resins using chromium, Ziegler-Natta or metallocene catalysts. Reducing the amount of fluoropolymer increases the matte nature of the polymer finish, whereas increasing the amount of fluoropolymer increases the gloss nature of the finish. Introducing a peroxide or air in an increasing amount increases the long chain branching (LCB) of the polymer. Introducing an antioxidant in an amount to balance the peroxide amount can improve the melt strength of the polymer, and the amount of antioxidant is balanced with the amount of peroxide and/or air. The resultant polymer density ranges between about 0.960 and 0.962 g/cm3 inclusive, where the molecular weight distribution (MWD) of the polymer is greater than 3 and less than 6.

A wind-driven spinner is provided. The wind-driven spinner embodies a rotatable display that enables customizable, holographic effects to capture the eye, while also providing adjustable stability and wind capturing controls. The wind-driven spinner may include a plurality of panel assemblies rotatably mounted to an axis shaft by means of two hub bearings. Each panel assembly may be paraboloid shaped so as to provide a leading edge and a trailing edge. Relative to the axis shaft, the leading edge of each panel assembly has a radial outer diameter greater than the radial outer diameter of its trailing edge and an adjacent panel assembly so as to provide at least one, adjustable wind-driven capture profile. Each panel assembly may include a customizable design sheet for providing graphic display area and holographic fabric.
