  • Patent number: 4636436
    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.

  • Patent number: 4578428
    Abstract: Olefinic polymers characterized by the presence of free carboxylic groups arranged along the polymeric chain, obtained by radicalic grafting of unsaturated carboxylic acids onto the chain of the olefinic polymer. The products so obtained exhibit in particular a high adhesion to metals. The manufacturing process is based on the use of at least two different organic peroxides, having different reactivities.
