Acid-modified synthetic polyamides

Synthetic polyamides (nylons) which have been mixed in the melt with from 0.1 to 5 % by weight of one or more compounds of the formula I R (-A-Bn)m in which R is a radical of a compound which is reactive towards hydroxyl and amino groups, A is a radical of an aromatic compound, B is a carboxyl or su...

More Information
Summary:Synthetic polyamides (nylons) which have been mixed in the melt with from 0.1 to 5 % by weight of one or more compounds of the formula I R (-A-Bn)m in which R is a radical of a compound which is reactive towards hydroxyl and amino groups, A is a radical of an aromatic compound, B is a carboxyl or sulphonyl group, m is 1 or 2, and n is 1, 2 or 3, give, when dyed with basic dyes, very bright and intense dyeings having very good wet-fastness properties.
