  • High strength and modulus polyvinyl alcohol fibers and method of their preparation
    Patent number: 4713290
    Abstract: Polyvinyl alcohol of molecular weight over 500,000 (i.e. 1,500,000 to 2,500,000) is spun as a dilute solution (2-15%) in a relatively non-volatile solvent such as glycerin. The resultant gel fiber is extracted with a volatile solvent such as methanol and dried. Upon stretching at one or more stages during the process, fibers of tenacity above 10 g/denier and modulus above 200 g/denier (e.g. 18 and 450, respectively) are produced.

  • Rotational molding multilayered articles
    Patent number: 4548779
    Abstract: A method of rotationally molding a multi-layered article. The outer layer is first rotationally molded and solidified.

The outer layer polymer has a melting point higher than the inner layer polymer. The outer layer is rotationally molded and cooled to below its melt temperature but above the melt temperature of the inner layer polymer. The inner layer is then rotationally molded while the outer layer remains solid.
