The composition of fatty acids synthesized de novo by thirty strains of zygomycetes from various taxa was studied. The qualitative fatty acid compositions of the fungal lipids were found to be virtually identical, but there were significant differenc

It was shown that incorporation of bromine in the aromatic rings of POD increases the light resistance of fibres. The effect of increasing the light resistance of bromine-containing POD fibres is due to quenching of the photoexcited triplet state of

The possibility of using bromine-containing terephthalic acids as monomers for the preparation of fire-resistant fibres has been examined. Satisfactory fibre physicomechanical properties are achieved at a bromine content up to 36%. Films and fibres b

A connection has been found between the bromine content of a polymer and its thermal stability, combustibility, and smoke evolution of oksalon fibres. At a bromine content of 4–5% by wt., a sharp increase in heat stability and smoke evolution is ob
