Poly(phenylenediamine) Dispersions

Journal of Colloid and Interface Science, 2001
The formation and properties of poly(phenylenediamine) colloidal dispersions were investigated. Oxidative dispersion polymerization of 1,3-phenylenediamine dihydrochloride stabilized with poly(N-vinylpyrrolidone) was taken as a reference experiment. Conductivity, temperature, and acidity of the reaction mixture were recorded during the polymerization ...

Sensitization to p-Phenylenediamine

Archives of Dermatology, 1965
p-Phenylenediamine (PPD) from 0.2 mg to 1.6 mg in water or in petrolatum was applied as a patch test to 501 patients with different dermatoses, asthma, hay fever, and venereal diseases. Of these patients 10.6% reacted within the first five days indicating previous hypersensitivity and 14.4% between the sixth and the 16th day indicating the initiation ...

Aniline-phenylenediamine copolymers

Synthetic Metals, 1999
The electrical conductivity of materials based on polyaniline can be controlled on submolecular level by the copolymerization of aniline with various phenylenediamines. The joint chemical oxidation of aniline with phenylenediamines yields products with the dc conductivity spanning over more than eleven orders of magnitude.

p-Phenylenediamine sensitization and occupation

Contact Dermatitis, 2010
p-Phenylenediamine (PPD) is an extreme delayed-type skin sensitizer, and is relevant in both occupational and non-occupational exposures.To estimate the prevalence of PPD sensitization in a population of consecutive patients with suspected allergic contact dermatitis who attended units of dermatology or occupational medicine in north-eastern Italy and ...

Polymers of phenylenediamines

Progress in Polymer Science, 2015
Abstract The chemical or electrochemical oxidation of phenylenediamines in acidic aqueous media yields the corresponding oligomers or polymers. Their structures and properties are discussed in relation to a closely-related conducting polymer, polyaniline.

Coordinating ability of phenylenediamines

Coordination Chemistry Reviews, 1999
Abstract The coordinating ability of aromatic diamines is conditioned both by the low basicity of the nitrogen atoms and their situation in ortho, meta or para positions on the aromatic ring. Important aspects of the aromatic diamines taking into account their possible applications are: processes based on electron transfer forming Wurster type ...

Spectrophotometric determination ofm-phenylenediamine

Mikrochimica Acta, 1969
A mixture of chloranil and cupric chloride-triphenylphosphine complex in acetone gives pinkish red color withm-phenylenediamine which provides the basis of a new spectrophotometric method for the determination ofm-phenylenediamine in minute quantities,o- andp-phenylene-diamines do not interfere with the determination if their amount does not exceed 90 ...
