A polycarbonate resin of a copolymer of diethyleneglycol bis(allyl carbonate) with one of glycidyl acrylate and glycidyl methacrylate, its homopolymer and its copolymer, and further occasionally a copolymerizable compound can be easily modified with active amine at its surface, and the surface-modified copolymer of diethylene glycol bis(allyl carbonate) with glycidyl acrylate or methacrylate can be easily dyed with acid dye in a sharp color tone and can be used in an optical instrument demanded to have a high vividness of color.

Method for modifying the surface of polycarbonate resin

A lubricating oil composition for metal rolling is described, comprising (a) an oily component comprising one or more of fats and oils, mineral oils, and fatty acid esters, and (b) a dispersant comprising one or more of polyethyleneimine/epoxy compound adducts, polyethylene polyamine/epoxy compound adducts, fatty acid esters of the adducts, and salts of the adducts and the fatty acid esters. This composition is useful for rolling metals under high shear and high rolling speed conditions.

Lubricating oil composition for metal rolling

A method for preparing a coal-water slurry is described, comprising the divided addition of dispersing agent or multi-step addition of dispersing agent during grinding in a process for preparing a coal-water slurry by the wet grinding of coal in water.

Method for preparing coal-water slurry

The cold flow of fuel oils is improved by adding esters of addition products of epoxides of specifically limited nitrogen-containing compounds with linear saturated fatty acids or a combination of the esters and polymers of one or more monomers selected from the group consisting of olefins, alkyl esters of ethylenically unsaturated carboxylic acids and vinyl esters of saturated fatty acids to fuel oils.

Method for improving cold flow of fuel oils

The cold flow of fuel oils is improved by adding esters of nitrogen-containing compounds having polyhydroxyl groups with linear saturated fatty acids or a combination of said esters and polymers of one or more monomers selected from the group consisting of olefins, alkyl esters of ethylenically unsaturated carboxylic acids and vinyl esters of saturated fatty acids to fuel oils.
