摘要:
Heavy oil or crude oil spills in sea water are recovered without polluting environment. A natural rubber latex and a coagulant are scattered around lumps of oil spills to coagulate the latex with the coagulant, so that a membrane of the latex is formed around the oil lumps.
摘要:
There is provided a method of removing acids from the surface and interior of an acetate film produced by deterioration during storage. Such methods are characterized by extracting and removing the acids from the surface and interior of the acetate film, and the extraction treatment includes solvent extraction or evacuation (heating). This method suppresses the deterioration process in the storage of the acetate film.
摘要:
A resin composition to be used as a material for a various part of an automotive vehicle. The resin composition comprises a copolymer (A) formed by copolymerization of a first unsaturated monomer (a) and a second mononer (b). The first unsaturated monomer has a functional group which is bondable by hydrogen bond to a hydroxyl group. The second monomer is copolymerizable with the first unsaturated monomer. A metal oxide (B) is dispersed in the copolymer and having hydroxyl groups and hydrophobic groups at surface of the metal oxide.
摘要:
A resin composition of the present invention comprises a polymer having functional groups and a metal oxide surface modified to form functional groups at a surface of the metal oxide and dispersed uniformly in the polymer. The functional groups of the polymer and the functional groups of the metal oxide are ionically bondable to the metal oxide and the polymer, respectively, so that the polymer and the metal oxide are bonded by ionic bonds to each other.
摘要:
A lithium ion conductive material that excels in mechanical strength, exhibiting high ion conductivity; a bacterial cellulose composite material having an inorganic material and/or organic material incorporated therein; and a bacterial cellulose aerogel. The water of bacterial cellulose hydrogel is replaced by a nonaqueous solvent containing a lithium compound. Bacterial cellulose producing bacteria are grown in a culture medium having an inorganic material and/or organic material added thereto. The bacterial cellulose hydrogel is dehydrated and dried.
摘要:
The invention relates to a porous nano material polymer composite. The porous nano material polymer composite according to the invention is prepared by impregnating monomer in the nanometer order holes of a nano material by supercritical carbon dioxide fluid, and by polymerizing the monomer in situ. Therefore, the polymer composite has a network structure in which polymer penetrates into nano pores.

摘要:
An ethylene-vinyl alcohol copolymer, represented by the formula (1): wherein n represents a number in the range of 15 to 15,000, and a method of producing an ethylene-vinyl alcohol copolymer wherein an 1,4 -polybutadiene is hydroborated in non-gel state in a solvent, followed by oxidation to be hydroxylated so as to derive an ethylene-vinyl alcohol copolymer represented by the formula (1): wherein n represents a number in the range of 15 to 15,000.
摘要:
A new polyurethane as well as a process for preparing same is disclosed. The new polyurethane contains therein a hard segment derived from at least one polyhydroxy substance selected from the group consisting of cellulosic substances, hemi-cellulosic substances and lignic substances, and is excellent in mechanical and thermal characteristics as compared with the existing polyurethanes. The new polyurethane can be prepared according to a method known per se, using the polyhydroxy substance alone or in mixture with a polyol compound as reactants to be polycondensed with a polyisocyanate.
