  • Catalytic distillation oligomerization of vinyl monomers to make polymerizable vinyl monomer oligomers uses thereof and methods for same
    Patent number: 6004256
    Abstract: This invention discloses a process for making polymerizable and/or reactable vinyl monomer oligomers with narrow molecular weight distributions using catalytic distillation and a catalyst situated in an immobile catalyst bed in a reaction zone of the distillation column reactor. The polymerizable oligomer products comprise at least 50% by weight of a single molecular weight oligomer fraction.

  • Quick-release fasteners
    Patent number: 3952626
    Abstract: A quick-release fastener device for fitment to the shank of a screw, stud or pin or the like device. The fastener is characterized by the provision of a collet member, which is composed of a number of segmental collet elements, and a retaining member which surrounds the collet member to retain the elements thereof in a cooperative relationship. The collet member is displaceable within or from the retaining member to permit separation of the collet elements one from the other and, hence, to permit quick release of the fastener from a device to which it is fitted.
