Polyamide Admixed With Oxyalkylene-containing Polymer Patents (Class 525/927)
  • Patent number: 8067524
    Abstract: The present invention uses hydrophobically modified polyaminamide with standard wet strength agent to produce a softer and more absorbent paper material. The hydrophobically modified polyaminamide is substantive to cellulosic fibers, thus is able to carry polyethylene glycol esters or ethers, a non-substantive material to cellulosic fiber as stable complexes, into the paper product.

  • Patent number: 4666995
    Abstract: The black speck formation which occurs during the compounding and molding of admixtures of oxymethylene polymers and polyamides having a melting or softening point below that of the oxymethylene polymer can be reduced by adding the polyamide to the oxymethylene polymer as a dispersion of the polyamide in a carrier resin which is inert to the oxymethylene polymer and has a melting or softening point below that of the oxymethylene polymer. The polyamide comprises less than about 50 weight percent of the dispersion.

  • Patent number: 4294944
    Abstract: Flame-retardant antistatic polymer additives are provided which inhibit the buildup of electrostatic charges upon the addition of such compositions to synthetic polymeric fibers, i.e., polyamide fibers, and at the same time do not contribute to the flammability characteristics of such polymeric fibers. The flame-retardant antistatic polymer compositions are useful in combinations with fibers such as polyamide, polyester, polyurea, polyurethane, polysulfonamide, polyolefin and polyacrylic fibers. The antistatic effect is obtained by the process of coating the fibers or dispersing in or on the fibers up to about 12 percent by weight of a polymer composition which is the reaction product of:(a) a polyoxyalkylene compound or polyester thereof and(b) at least one reactant selected from the group consisting of (1) a diol, (2) a polyester and (3) an aliphatic or aromatic diacid or derivative of (3), wherein at least one said reactant is halogenated.
