  • Method of increasing polymerization reaction rates in the production of a fiber-thermoplastic matrix by in situ bulk polymerization
    Patent number: 4148949
    Abstract: A method of increasing polymerization reaction rates during the production of a fiber-thermoplastic matrix by in situ bulk polymerization is described, allowing polymerization to at least 25% polymer content by weight of the matrix in less than 8 minutes. In a fibrous web of less than 0.
    Type: Grant
    Filed: February 13, 1978
    Date of Patent: April 10, 1979
    Assignee: Weyerhaeuser Company
    Inventors: Richard R. Casper, Myron P. Marander
  • Method of controlling monomer loss during the production of a fiber-thermoplastic matrix by in situ bulk polymerization
    Patent number: 4051214
    Abstract: An improved method of controlling monomer loss during the production of a fiber-thermoplastic matrix by in situ bulk polymerization is described, the improvement allowing polymerization to greater than 25% polymer content by weight of the matrix within less than eight minutes. A fibrous web of less than 0.25-inch thickness, saturated with a liquid phase polymerizable composition containing a vinyl monomer and a thermally activated free radical initiator at 1/2-10% by weight of the composition is polymerized under controlled conditions in which the matrix is: (a) confined between heat transfer surfaces at 0.
