Abstract
Hydrophilic textile fibers, which exhibit good receptivity to dyes of the disperse class are prepared from crystalline olefin polymers modified by carboxylic acids, grafted along the polymer chain, by reaction with polyamides, polyamines, polyoxyethylene alcohols or polyoxyethylene amines which react with the carboxylic acids and processes for obtaining such fibers are disclosed.
Claims8
Fibers and films comprising the reaction product of (1) a crystalline olefin homopolymer or copolymer modified with an unsaturated carboxylic acid and (2) a compound reactive with the carboxylic groups and selected from the group consisting of polyamides, polyamines, polyoxyethylene alcohols of the general formula
- R--O(CH.sub.2 CH.sub.2 O).sub.n H
- and polyoxyethylene amines of the formula
- R--N[(CH.sub.2 CH.sub.2 O).sub.n H].sub.2
- in which general formulae R is an alkyl radical containing 1 to 18 carbon atoms and n is an integer ranging from 1 to 50.
