摘要： An elastic material for use in an absorbent article is provided. The elastic material contains a crosslinked network formed from a linear block copolymer having a monoalkenyl aromatic midblock positioned between conjugated diene endblocks (e.g., butadiene-styrene-butadiene (“B-S-B”) triblock copolymer). Prior to crosslinking, such linear block copolymers have a relatively low viscosity and thus may be readily formed into a precursor elastic material (e.g., film, strands, web, etc.) that is subsequently crosslinked to achieve the desired elastic and mechanical properties. Crosslinking is typically achieved through the formation of free radicals (unpaired electrons) that link together to form a plurality of carbon-carbon covalent bonds at the conjugated diene endblocks.

摘要： The present invention relates to an improved disposable cleaning sheet for removing debris, especially hair from a non-smooth or rough surface, especially fibrous type surfaces such as carpeting or upholstery. The cleaning sheets comprise a fibrous substrate and a plurality of protrusions extending from strand elements embedded within fibrous substrate. The cleaning sheets use the protrusions to dislodge the debris from the surface being cleaned, and the fibrous substrate captures the dislodged debris without a backing for the protrusions interfering with the particle capture of the fibrous substrate. Further, the protrusions are firmly embedded within the fibrous substrate such that they cannot be dislodged from the substrate in use.

摘要： An electrical substrate material is presented comprising a thermosetting matrix of polybutadiene or polyisoprene and a co-curable second resin distinct from the first resin. A peroxide cure initiator and/or crosslinking agent may optionally be added. The presence of a very high surface area particulate filler, preferably fumed silica, is also preferred, in that its presence results in a prepreg which has very little tackiness and can therefore be easily handled by operators. This low tackiness feature allows for the use of conventional automated layup processing, including foil cladding, using one or more known roll laminators. While the prepreg of this invention is tack-free enough to be handled relatively easily by hand, it is also tacky enough to be tacked to itself using a roll laminator (e.g., nip roller) at room temperature. The composition of this invention is particularly well suited for making electrical circuit substrates for microwave and digital circuits, typically in the form of the thermosetting composition being laminated onto one or both opposed surfaces to a metal conductive foil such as copper.

摘要： An adsorbent filter for removing caffeine from liquids. The filter is composed of a liquid permeable matrix of fibrous material having individual exposed surfaces; and a distribution of adsorbent clay minerals attached to individual exposed surfaces of the fibrous material by substantially non-transient bonding, so that passage of a liquid having a caffeine concentration ranging from about 20 to about 100 mg per 100 mL of liquid through the matrix for a contact time of less than about 2 minutes results in at least a 40 percent reduction in the caffeine concentration of the liquid. The matrix of fibrous material may be selected from woven fabrics, knit fabrics and nonwoven fabrics. The adsorbent clay minerals include, for example, sodium bentonite clays, calcium bentonite clays, acidified bentonite clays, and modified bentonite clays containing a flocculating agent. Generally speaking, the filter can be adapted to provide at least a 40 percent reduction in the caffeine concentration for about 1 cup to about 40 cups of a liquid.

摘要： The present invention relates to an X-ray absorbing material that can be used in medicine as well as in the manufacture of special protective clothing, protective screens, housings, protective coatings and isolation materials. In a first embodiment, the material uses as a filler a poly-dispersed mixture, segregated by kneading and containing metallic particles having a size between 10−9 and 10−3 m, wherein the particles are bonded to the surface of a textile base. The density of the material is defined by the relation qN=(0.01–0.020) qP, where qN is filler. In a second embodiment, the invention uses as a filler the above mixture, although here the particles are surrounded by the volume of a matrix made of a compound that solidifies under atmospheric pressure. The total mass of the poly-dispersed and segregated mixture is defined by the relation M=(0.05–0.5)m, where M is the total mass of the X-ray absorbing poly-dispersed and segregated filler, while m is the equivalent mass of the filler material that is equal in protective properties to the mass M. In a third embodiment, the invention uses as a filler the above mixture with the particles bonded to an intermediate substrate consisting of a textile base and surrounded by the volume of a matrix.

Preferred ethylene propylene rubbers are ethylene propylene copolymers and ethylene propylene diene terpolymer rubbers wherein the diene is dicyclopentadiene. The ethylene propylene rubber is present in an amount of up to about 20 wt % with respect to the resin, preferably in an amount of about 1 to about 7 wt %, more preferably about 5 wt %. The presence of the ethylene propylene rubber enhances the dielectric strength of the resulting electrical substrate material, while other electrical, chemical, and mechanical properties of the material are not adversely effected.

摘要翻译： 提供了一种电气基材材料，其包括热固性基质，其包括聚丁二烯或聚异戊二烯树脂，不饱和丁二烯或含异戊二烯的聚合物和乙丙橡胶; 颗粒填料和织物。 优选的乙烯丙烯橡胶是乙烯丙烯共聚物和乙烯丙烯二烯三元共聚物橡胶，其中二烯是二环戊二烯。 乙烯丙烯橡胶相对于树脂的量最多为约20重量％，优选为约1至约7重量％，更优选约5重量％的量。 乙丙橡胶的存在增强了所得电气基材材料的介电强度，而材料的其它电学，化学和机械性能也不会受到不利影响。
