  • Polyamides
    Patent number: 4191669
    Abstract: Polyamides suitable as hot-melt adhesives and containing groups derived from a polymeric fatty acid containing 70-90% by weight of dimer acid and from a triamine of the structure ##STR1## in which R.sub.1 is a C.sub.1 -C.sub.3 alkyl group and R.sub.2 and R.sub.3 are bivalent hydrocarbon radicals. Optionally the polyamide also contains groups derived from a C.sub.2-20 diamine, a dicarboxylic acid containing 6-12 carbon atoms, a monocarboxylic acid or a C.sub.5-12 lactam.

  • Aluminous metal sheet
    Patent number: 4157422
    Abstract: This invention relates to useful protective compositions, a method for protecting aluminum and aluminum alloy products against water staining, and a protected aluminum sheet. The method involves applying a continuous film of a protective composition to the surface of the aluminum product. The protective compositions useful for the invention are blends or reaction products of a polybasic acid and a partial ester of a polyol.

  • Method for treating polymeric fibers
    Patent number: 3959560
    Abstract: Ester lubricant compositions are provided which provide a good balance of lubricity and emulsifiability. The esters are derived from polyoxyalkylene glycols with a dibasic acid mixture consisting of dimer acids and short-chain dibasic acids. The emulsions and clear, homogeneous lubricant solutions provide excellent spin finishes for fibers such as polyamides and polyesters.
