摘要:
A transition metal compound in powdered form or a mixture of a transition metal compound and other inorganic compounds in powdered form can be effectively coated with a polymer by contacting such powder with a vinyl monomer in the presence of hydrogen sulfite ions (HSO.sub.3 .sup.-).
摘要:
A reinforcing composition for mineral structures which comprises as reactive ingredients one or more radical-polymerizable or copolymerizable monomer and a bisulfite ion-supplying substance. The use of the reinforcing composition facilitates reinforcement of natural or artificial mineral structures and products.
摘要:
Dry process for the production of inorganic granular substances coated with plastics, characterized in that a radical-polymerizable vinylic monomer carried on the surface of an inorganic granular substance is brought in a gaseous phase into contact with gaseous sulfur dioxide to effect polymerization of the monomer. The resulting plastic-coated inorganic substances are useful in various fields of industry, for example, as fillers, construction materials, molding materials, electrode materials, delayed-action fertilizers, etc.
摘要:
A method of manufacturing reinforced resin moldings, wherein a fiber-reinforced plastic, obtained by the polymerization, in the presence of an inorganic fibrous substance selected from the group consisting of glass fiber, slag wool and asbestos, of a vinyl monomer, within an aqueous medium in the presence of sulfur dioxide, said fiber-reinforced plastic being composed of 5 - 50 wt.% of resin and 95 - 50 wt.% of inorganic substance and coated with a polymer, is subjected to compression molding.
摘要:
Particulate solids are coated with a polymer by bringing a particulate solid selected from glass particles, abrasive particles and sand particles into contact with a vinyl monomer in the presence of a polymerization intiator consisting essentially of bisulfite ions.
摘要:
Metal powder is suspended in an aqueous medium containing a radical-polymerizable monomer and polymerization is conducted in the presence of an acidic sulfite ion to produce a plastic coated metal powder which is effectively used for forming conductive plastics, molded articles for sintering, pressed powder magnetic cores and the like.
摘要:
A hardenable molding composition comprising hydratable gypsum, a vinyl monomer, a source of hydrogen sulfite ions and water is disclosed. With this molding composition a hardened product can be obtained having high strength due to the combined effect of the hydraulic reaction of the gypsum and the polymerization reaction of the vinyl monomer.
摘要:
The present invention is a power storage device including a holding member holding power storage units and temperature detection sensors detecting temperatures of the power storage units held by the holding member, in which the holding member includes a facing surface portion facing coated surfaces of the power storage units held by the holding member, and through holes formed so as to pierce through the facing surface portion, each of the temperature detection sensors includes a lid unit closing the through hole by being attached to the holding member, and a sensor unit supported in the lid unit so as to be elastically deformed, which is elastically deformed when the lid unit closes the through hole, pressed and contacted onto the coated surface of the power storage unit due to reaction force of elastic deformation.
