  • Printing blanket containing a high elongation fabric
    Patent number: 5066537
    Abstract: The present invention relates to improved compressible, offset printing blankets suitable for use on high speed web processors. These blankets have improved resistance to fall-off at the gap and also have improved resistance to surface piping subsequent to reverse rolling of the blanket. The instant printing blanket comprises a carcass layer, a compressible layer overlaying the carcass layer, a stabilizing layer overlaying the compressible layer and an ink transfer layer upon the compressible layer, wherein the stabilizing layer is formed of a fabric having a plurality of continuous filament synthetic warp yarns, preferably nylon or polyester, following a sinusoidal path over and under the weft yarns.

  • Monomer-plasticized elastomers and process for producing same
    Patent number: 4689273
    Abstract: Elastomers are plasticized with a polymerizable monomer, in homogeneous admixture therewith, by adding the monomer to a latex of the elastomer, free of polymerization initiator, followed by coagulation of the monomer and polymer solids. The coagulated solids recovered from the latex may be compounded with a polymerization initiator for the monomer and a vulcanizing agent for the polymer and, optionally, an inorganic filler, and shaped into the desired product form. Polymerization of the polymer and vulcanization of the elastomeric polymer are initiated after shaping.
