Abstract
Amino-poly(imidazoline-amide) compositions are disclosed which are useful for occlusion in polyolefins to render them dyeable with acid textile dyes. Polyolefins are useful in textile fibers or filaments. The compositions are certain azelaic acid, polyamide-imidazoline products of a mixture of diethylene triamine and a diamine. Optionally, fatty compounds such as a dimeric fat acid or monomeric fatty acid or another, different aliphatic dicarboxylic acid may be present.
Claims9
An amino-poly(imidazoline-amide) having a total amine number of at least 75 and a tertiary amine number of at least 50, formed as the reaction product at a temperature and time sufficient to provide said tertiary amine number of
- a. from about 20-50 equivalent percent of azelaic acid,
- b. up to about 20 equivalent percent of another, different, aliphatic, dicarboxylic acid having from 6 to 12 carbon atoms,
- c. up to not more than 6 equivalent percent of a dimeric fat acid,
- d. up to not more than about 10 equivalent percent of a monomeric, monocarboxylic fatty acid having from 16-22 carbon atoms,
- e. about 25-40 equivalent percent of diethylene triamine and
- f. about 15-30 equivalent percent of an alkylene diamine having 2-6 carbon atoms wherein the sum of said equivalents percent total 100 and the sum of amine equivalents percent is at least about equal to the carboxyl equivalent percent and the equivalent percent of diethylene triamine is at least about equal to the equivalent percent of said diamine, provided further that where a mixture of said dimeric fat acid and said monomeric fatty acid is employed the total equivalent percent of said mixture shall not exceed 11 equivalent percent.
