    Abstract: Incorporation of at least one lubricant and an ethylene-based polymer of the formula E/X/Y wherein E is ethylene, X is methyl acrylate, butyl acrylate, or ethyl acrylate, and Y is glycidyl methacrylate, glycidyl acrylate, or glycidyl vinyl ether into polyacetal compositions results in compositions having good wear resistance and good melt processing thermal stability. The compositions are useful, for example, when molded into parts to be used in sliding applications, such as gears, cams, and conveyor chains.

  • Patent number: 5324762
    Abstract: The subject of this invention is acrylic polymer plastisol compositions, wherein the acrylic polymer component of the plastisol composition is a single-stage methyl methacrylate copolymer derived from methyl methacrylate and a comonomer component comprising isobutyl methacrylate and optionally other comonomer(s). The selection of isobutyl methacrylate as a comonomer with the methyl methacrylate results in good compatibility with a wide range of plasticizers and without undue softness in the resulting plastisol.
