Abstract: A composition including a thermoplastic resin, and a combustion accelerator composed of an inorganic carrier and a platinum group element supported on the inorganic carrier in an amount of 0.001-0.2% by weight based on a total weight of the inorganic carrier and the platinum group element. The combustion accelerator is in the form of particles and present in such an amount that the concentration of the platinum group element is 0.5-100 ppm by weight based on a total weight of the combustion accelerator and the thermoplastic resin.

Abstract: A resin composition containing 100 parts by weight of a thermoplastic fluorine-containing resin, 1-40 parts by weight of polymer-grafted carbon black, 1-15 parts by weight of a thermoplastic polyether resin, and 0-2 parts by weight of an electrolyte. An endless seamless belt having the above composition is suited as an intermediate image transfer element for an electrophotographic image forming apparatus.

Abstract: A biodegradable film or the like shaped article is formed from a composition including 100 parts by weight of cellulose fibers having a length of 3 mm or less and a diameter of 50 .mu.m or less, 10-600 parts by weight of a thermoplastic resin and 2-100 parts by weight of chitosan. A mixture containing (a) an aqueous solution of an acid salt of chitosan, (b) an aqueous dispersion or solution of a thermoplastic resin and (c) fine cellulose fibers is dried and shaped to obtain such a biodegradable shaped article.

Abstract: A biodegradable sheet is produced from an aqueous dispersion containing finely cut cellulose fibers and chitosan. The dispersion is maintained at a temperature T.sub.1 .degree.C. which is within the following range:t.ltoreq.T.sub.1 .ltoreq.t+30wherein t is the boiling point (.degree.C.) of water at a given reduced pressure and is continuously introduced into a defoaming zone maintained at the given reduced pressure and at a temperature within the same range as that of T.sub.1. In the defoaming zone, the dispersion is formed into a downwardly flowing laminar flow so that air entrapped therein is effectively removed therefrom. The defoamed dispersion is then passed through a die and is molded into a sheet which is subsequently dried.

Abstract: There are provided a radical polymerizing composition giving a cured resin having excellent elasticity which comprises a mixture of two or more kinds of monomethacrylic acid esters having specific structure at specific mixing ratio and organic peroxide, and more particularly an anaerobic liquid gasket having excellent sealing properties, pressure resistance and good storage stability which comprises these polymerizing composition, filler, anaerobic curing accelerator and stabilizer.

Abstract: A novel anaerobically curable resin composition of one-part type is provided. The composition consists essentially of the following components (a), (b) and (c) in the specified amounts; the component (a) being a mixture of polymerizable components consisting of (i) an addition-reaction product of a polybutadiene-based liquid rubber, a polyisocyanate and a hydroxyl group-containing methacrylate, and (ii) a polymerizable methacrylate; the component (b) being a salt of o-benzoic sulfimide with a specified amine; and the component (c) being an ammonium or amine salt of an aminopolycarboxylic acid. The process for preparation of the composition comprises the step of adding the specified amounts of the aminopolycarboxylic acid or an alkali metal salt thereof and an ammonia water or a volatile organic amine to the component (a), the step of stirring and heating the mixture to remove volatile matters partly until the pH is decreased to 9 or lower, and the step of adding thereto the component (b).
