Influence of diaminomaleodinitril on quality of galvanic nickel coverage was investi-gated. Structure and physical-chemical properties of nickel coverages were studied. It was established that diaminomaleodinitril introduced to standard electrolyte of nickel-plating (10 – 50 mg/l) is the effective brightener. The light-reflecting ability of the nickel-plating reaches of 82 %. The roughness of nickel coverage is reduced by a factor of 2.5. The electrolyte sca-ter ability is increased by a factor of 2.

Key words: electrochemical nickel-plating, electrolyte, brightener addition

SYNTHESES OF ω -Н-PERFLUORINE CARBOXYLIC ACIDS BY OXIDATION OF ALCOHOL-TELOMERS H(CF2CF2)nCH2OH

Methods of synthesis of ω-Н-perfluorine carboxylic acids by oxidation of alcohol-telomers of H(CF2CF2)nCH2OH (n = 1 – 4) composition were developed. Physical-chemical properties of poly fluorinated alcohols and carboxylic acids were determined.

Key words: poly fluorinated alcohols- telomers, ω-Н-perfluorine carboxylic acids
