摘要： Blend compositions containing a novel homopolymer, the use of which allows the incorporation of more comonomer in the additional components of the blend (for the same overall density) resulting in increased tie molecule formation and improvement in properties such as ESCR, toughness and impact strength are disclosed. The homopolymers are important for applications where a high density is needed to ensure certain mechanical properties like abrasion resistance, indentation resistance, pressure resistance, topload resistance, modulus of elasticity, or morphology (for the chlorination of PE to CPE) and additional advantages such as melt processability. The blend can be obtained by dry or melt mixing the already produced components, or through in-situ production by in parallel and/or in series arranged reactors. These resins can be used in applications such as films, blow molded, injection molded, and rotomolded articles, fibers, and cable and wire coatings and jacketings and, various forms of pipe.

摘要： An assembly is described for connection to a borescope to simultaneously provide a virtual image for direct viewing by an observer and a video image for viewing on a display. The assembly (10) comprises a body (12) with a distal end for connection to an insertion tube of a borescope and a proximal end providing an eye piece into which an observer may look. The body contains a relay lens (16) and an ocular lens (18). A beam splitter (28) is mounted in the optical path between the relay lens (16) and the ocular lens (18) and diverts a proportion of light received from the relay lens (16) to an image-to-video conversion device (30) mounted laterally to the optical path. The ocular lens (18), beam splitting device (28) and the image-to-video conversion device (30) are all located in a common mounting (38) which can be translated in a direction parallel to the optical path to allow for focussing.

摘要： A polymer produced by a transition metal containing catalyst useful for the polymerization of &agr;-olefins is prepared by (A) forming in an inert atmosphere which excludes oxygen and moisture a slurry of (1) a porous inorganic oxide support material selected from the group consisting of silica, alumina, or a combination of silica and alumina, said support material containing not greater than about 5 millimoles of hydroxyl groups per gram of support material and a particle size not greater than about 10 microns and a surface area of from about 50 to about 800 m2/g in an inert organic liquid medium; (B) mixing said slurry with (2) an alkoxide and stirring the resultant mixture at a temperature of from about −20° C. to about 120° C. for a time sufficient to saturate the surface of the support material; (C) mixing the product form (B) with (3) a titanium compound or a combination of a titanium compound and (4) a vanadium compound and stirring the resultant mixture at a temperature of from about −20° C. to about 120° C. for a time sufficient to allow complete reaction of the titanium compound and the vanadium compound with the organomagnesium moieties remaining on the solid support; (D) mixing the product from (C) with an inert organic solution of (5) a Group IIIA metal alkyl halide at a temperature of from about −20° C. to about 120° C. for a time sufficient to complete the reduction of the titanium and vanadium, if present, compounds to their final oxidation state. Ethylene/alpha-olefin copolymers which have greater than 17 percent high density fraction and a Mw/Mn ratio of less than about 3.6 are shown to be useful in making cast films which have good stretchability and good puncture resistance. Copolymers of the present invention having the specified properties are especially useful in making the films.
