A foam comprising a silicone based polymer as a base resin.

To provide a foam-molded product which is light-weight and superior in formability, flexibility and shock absorbing capacity, and which exhibits favorable tactile impression and excellent safety, as well as a shock absorber using the same that provides favorable feel in wearing.

Means for Resolution: When a foam-molded product is used which is produced by including foamed resin particles in a soft resin obtained from a silicone based polymer, as a base resin, produced by curing a liquid resin composition including: (A) a curing agent having at least two hydrosilyl groups in the molecular chain; (B) a polymer which has at least one alkenyl group in the molecular chain, comprises a saturated hydrocarbon unit or an oxyalkylene unit as a repeating unit that constitutes the main chain, and is a linear polymer having a number average molecular weight of no lower than 10,000; and (C) a hydrosilylation catalyst, the product can be suitably used in garments to which it is attached as a shock absorber at an appropriate site such as the front body, the flank part, the back body and the hip around the lumbar.

It is an object of the present invention to provide a proton-conducting membrane, excellent in resistance to heat, durability, dimensional stability and fuel barrier characteristics, and showing excellent proton conductivity at high temperature. It is another object of the present invention to provide a method for producing the same. It is still another object of the present invention to provide a fuel cell using the same.

The present invention provides a proton-conducting membrane, comprising a carbon-containing compound and inorganic acid, characterized by a phase-separated structure containing a carbon-containing phase containing at least 80% by volume of the carbon-containing compound and inorganic phase containing at least 80% by volume of the inorganic acid, the inorganic phase forming the continuous ion-conducting paths. The present invention also provides a method for producing the above proton-conducting membrane, comprising steps of preparing a mixture of a carbon-containing compound (D) having one or more hydrolyzable silyl groups and inorganic acid (C), forming the above mixture into a film, and hydrolyzing/condensing the hydrolyzable silyl group contained in the mixture formed into the film, to form a three-dimensionally crosslinked silicon-oxygen structure (A). The present invention also provides a fuel cell which incorporates the above proton-conducting membrane.

Spherical crosslinked organic particles exhibit a good dispersibility in thermoplastic resins, thermosetting resins, paints, coatings, cosmetics, rubbers, and toners and carriers employed in electrostatic development. Highly efficient methods for preparing these crosslinked organic particles are provided. Suspensions of crosslinked organic particles have excellent handling properties, and are highly blendable with other components. Highly efficient methods for preparing these suspensions are also provided. The spherical crosslinked organic particles have an average particle size of 0.1-500 µm, and can be prepared by emulsifying in water using an emulsifying agent, a fluid composition containing (A) an organic compound that has at least 2 aliphatically unsaturated bonds in each molecule, (B) a silicon-containing organic compound that has at least 2 silicon-bonded hydrogen atoms in each molecule, (C) an hydrosilylation reaction catalyst, crosslinking the fluid composition by carrying out an hydrosilylation reaction, and thereafter removing water.

This invention provides a foamable resin composition divided into two or more discrete mixing components and which is foamed and set by mixing said discrete mixing components each other,

   wherein said composition comprises

• (A) an organic compound having a viscosity of 20 Pa·s or less at 23 °C and having a carbon-carbon double bond,
• (B) a compound having a hydrosilyl group, and
• (C) a foaming agent having a boiling point of 100 °C or lower and/or a compound having an OH group,
  
     each of said two or more discrete mixing components comprises one or more of said components (A), (B) and (C) and has a viscosity of 5 Pa·s or less at 23 °C.

By preparing the two or more discrete mixing components having low viscosities and performing a foaming/setting process in which these discrete mixing components are sprayed or infused after mixing or with mixing, a foam having a high expansion ratio and a fine cell can be obtained.
