    Abstract: PURPOSE:To obtain the title polymer as a material for an inorganic fiber excellent in mechanical and thermal properties and conductivity, by bonding a specified organosilicon polymer to a block polymer through oxygen. CONSTITUTION:A precursor polymer obtained by reacting an organosilicon polymer with a polynuclear aromatic compound is reacted with a transition metal compound of the formula (wherein M is Ti or Zr and R is alkyl or phenyl) to obtain an organometallic polymer comprising an organosilicon polymer part comprising (Si-CH2) units (a) and (Si-Si) units (b), having side chain groups selected from among H, lower alkyls, phenyl and silyls as side chains of the Si atom, wherein the ratio of the total number of units (a) to the total number of units (b) is 1:0-20, and a part (c) which corresponds to said organosilicon polymer part in which at least part of the silicon atoms are bonded to M bonds through oxygen and a part (d) which corresponds to said organosilicon polymer part in which at least part of the silicon atoms are bonded directly to Ar bonds (wherein Ar is a polynuclear aromatic compound or its product of heat treatment), wherein the ratio of the total number of units (c) to units (d) is 2-500:1, and having a number-average MW of 500-100,000.

    Abstract: PURPOSE:To obtain a polyethylene foam having excellent flame retardance and mechanical characteristics, by using a composition obtained by compounding a polyethylene resin, aluminum hydroxide, magnesium hydroxide, chlorinated polyethylene and a lubricant at specific ratios, as a main raw material. CONSTITUTION:A composition composed of 30-60wt% polyethylene resin, 40- 15wt% aluminum hydroxide, 40-15wt% magnesium hyroxide, 1-10wt% chlorinated polyethylene, and 1-6wt% lubricant (e.g. metallic salt of lauric acid, etc.), wherein the weight ratio of aluminum hydroxide to magnesium hydroxide is 0.5-1.7, is mixed with a foaming agent (e.g. azodicarbonamide) and a crosslinking agent (e.g. dicumyl peroxide), and foamed by heating to obtain the objective flame-retardant polyethylene resin foam. USE:Flooring material and wall material.

    Abstract: PROBLEM TO BE SOLVED: To provide an electromagnetic wave absorber and a method of manufacturing the absorber, whose properties of absorbing electromagnetic waves are excellent through wide bands, and which has such great levels of specific tensile strength and specific modules that can be used as a structural material, and further which includes a composite material composed of an inorganic fiber containing a conductive inorganic material and an insulating matrix. SOLUTION: The absorber has a composite material composed of an inorganic fiber containing a conductive inorganic material and an insulating matrix. The fiber has the composite phase of a silicon carbide material and a conductive inorganic material. The existence percentage of the conductive inorganic material gets gradually larger at the outer layer. The layer portion, where the percentage of the conductive inorganic material gradually gets larger, is in a thickness between 1 nm and 500 nm.
