  • Free flowing particles of elastomeric material and method
    Patent number: 4233365
    Abstract: Elastomeric particles which are rendered free flowing by treatment with the combination of a finely divided partitioning agent and a fibrilatable polymer which has been fibrilated to form a network on the surface of the elastomeric material with retention of the partitioning agent thereby.
    Type: Grant
    Filed: April 6, 1979
    Date of Patent: November 11, 1980
    Assignee: Copolymer Rubber & Chemical Corp.
    Inventor: Rudolph F. Karg
  • Particulate elastomeric materials and method
    Patent number: 4213888
    Abstract: The preparation of elastomeric materials in the form of free flowing particles in which the latex formed by the polymerization of the monomers in aqueous medium is coagulated to produce particles of a size within the range of 0.5 to 5 millimeters and in which the particles are ultimatedly dried and then cooled while in a fluidized state and which includes the addition of partitioning agents to obstruct agglomeration.
    Type: Grant
