摘要:
A viscosity conditioner is disclosed which is comprised of a compound represented by the following formula where R 1 to R 3 each are hydrocarbyl groups which may be identical or different, m ranges from 2 to 4, and n ranges from 1 to 1,000. The specified viscosity conditioner is by nature non-ionic and excellent in leveling.
摘要:
An oil-in-water type emulsion comprising (1) an emulsifying agent, (2) a lysophospholipoprotein, and (3) a protein other than the lysophospholipoprotein (2), the protein (3) having a larger molecular weight than the protein (2); and a process for producing the same comprising preliminarily emulsifying a composition containing the emulsifying agent (1) and the lysophospholipoprotein (2), homogenizing the emulsion, and then adding the protein (3) to the homogenate, or comprising emulsifying a composition containing the emulsifying agent (1) and the lysophospholipoprotein (2) by means of a membrane emulsifier and then adding the protein (3) thereto.
摘要:
There is provided an urethane modified epoxy resin either obtained by reaction of 100 weight portions of a preliminary condensate [A] produced by reaction of an epoxy resin and an acid of a phosphorus compound or its salt or ester and 5 to 60 weight portions of an isocyanate group-terminated urethane prepolymer [B] produced by reaction of a hydroxy compound and an organic polyisocyanate compound, or obtained by preparing an urethane modified epoxy resin [D] from 100 weight portions of an epoxy resin and 5 to 60 weight portions of the same isocyanate group-terminated urethane prepolymer [B] as the above and causing the resin [D] to react with an acid of the same phosphorus compound as the above or its salt or ester. Such an urethane modified epoxy resin can advantageously be used with an active organic hardening agent to produce an adhesive resin composition, which is highly effective for bonding iron and non-ferrous metals particularly in terms of shearing strength and peeling strength.
摘要:
The heat-sensitive recording material of the present invention comprises a heat-sensitive recording layer containing at least one resorcylic anilide derivative represented by the following general formula: wherein R 1 represents an alkyl or alkoxy group having 1 to 4 carbon atoms and R 2 represents a hydrogen atom or an alkyl or alkoxy group having 1 to 4 carbon atoms.
摘要:
The present invention is directed to provide an engine oil composition which fully exploits the performance of molybdenum dithiocarbamate (MoDTC), restricts degradation of MoDTC itself, and has a high MoDTC residual property even at the time of degradation, hence providing low friction and low wear for a long time, and which results in savings in fuel consumption. It is also directed to an engine oil composition having a high coefficient of friction and an extreme-pressure property under fluid lubricating conditions arising from extreme-pressures, in order to solve various problems encountered in friction. The engine oil compositions according to the present invention comprise a specific MoDTC, a specific zinc dithiophosphate and a base oil for engine oil as the essential components, and specific polyglycerin half esters may be further added.
摘要:
An antifouling agent containing, as an active ingredient, one or more compounds represented by formula (I):
wherein R represents an alkyl group; R₁ represents an alkylene group; n represents an integer of 2 to 5; m and p each represent 0 or 1; X represents a nitro group, an alkyl group, an alkoxy group, a halogen atom or a hydrogen atom; and Y represents a nitro group or a halogen atom; provided that the sum of m and p is 1 or 2.
