โœฆ Synopsis

A~tract--Complexes have been prepared by the reactions of 2,6-diaminopyridine and 4-aminobenzoyl hydrazide with the chlorides of cobalt, nickel and copper in ethanolic solution. One of the compounds has a tetrahedral structure while the remaining compounds have polymeric octahedral structures. The initial decomposition temperature for each of the complexes was obtained from the thermogravimetric studies. The performances of the complexes as colouring materials for polyethylene has been investigated; weather resistance, light fastness, migration resistance and heat stability have been considered. The complex Co2(CsHTN3)C14 performed well in all tests and is a suitable material for development as a pigment for polyethylene.
