    摘要： Disclosed is a process for the preparation of 2,2'-bis(4-substituted phenol)sulfides which comprises reacting a 4-substituted phenol with sulfur dichloride in a hydrocarbon solvent at a temperature of from -10.degree. to 40.degree. C. in the presence of a Lewis acid catalyst. For example, 2,2'-bis(4-cumylphenol)-sulfide, i.e. 2,2'-bis(4-.alpha.,.alpha.-dimethyl benzyl-phenol)monosulfide, which is a novel compound can be prepared by reacting 4-cumylphenol with sulfur dichloride in benzene at a temperature of from 0.degree.to 10.degree. C. in the presence of zinc chloride.

    摘要： In a novel method of homo- or copolymerization of vinyl chloride, a specified coating agent is applied on the surfaces of the portions which will become into contact with the vinyl chloride monomer during the polymerization process. The coating agent is in a form of an aqueous solution of a modified condensation product of phenol and aldehyde, the pH of the solution being adjusted in a range that the product is dissolved at an ambient temperature upon coating of the solution and separates out of the solution upon being heated on the surfaces. The wall surface of the polymerization tank and the like is then coated with a thin film of the coating agent having a uniform thickness and being strongly adhered to the wall surface, thereby providing an excellent effect of preventing adhesion of the product polymer to the wall surface.

    摘要： Bis(3-nitrophenoxy) derivatives of aromatic or bridged aromatic hydrocarbons are derived from m-dinitrobenzene and dihydroxy derivatives of said hydrocarbons and certain substituted derivatives thereof by a condensation reaction in dipolar aprotic solvents in the presence of bases. The bis(3-nitrophenoxy) derivatives and derivatives obtained are successively reduced to afford bis-(3-aminophenoxy)derivatives. This is a new method for reacting the dihydroxy-derivatives with m-dinitrobenzene, and hence can prepare novel bis(3-aminophenoxy) derivatives such as 4,4'-bis(3-amino-phenoxy)biphenyl, 1-[4-(3-aminophenoxy)phenyl]-1,3,3-trimethyl-6-(3-aminophenoxy)indan, 6,6'-bis(3-aminophenoxy)3,3,3',3'-tetramethyl-1,1'spirobiindan, and methyl substituted 2,2'-bis[4-(3-aminophenoxy)phenyl]propane.
