Dye-receptive polyolefin mouldings prodn - by mixing polyolefins with condensates of substd amines with dicarboxylic acids, amino

摘要

Mouldings, such as fibres, films, tapes of olefin (co) polymers and nitrogenous condensates of 3-aminomethyl-3,5,5-trimethylcylclohexamine and aliphatic (e.g. succinic, adipic) acids, aromatic or isocyclic (e.g. terephthalic, isoterephthalic, hexahydroterephthalic) acid and/or amino acids or their lactams (e.g. aminoundecanoic acid, caprolactam), and extruding the mixture. Products are readily and evenly dyeable, and mechanical properties are not impaired by admixture of the condensates. The polyolefin may be isotactic polypropylene.
