  • Piston assembly for syringe
    Publication number: 20050010175
    Abstract: A piston assembly (10) for a flowable materials container having a barrel (14) defining a fluid containing chamber (16). The barrel (14) is made of a body of a cyclic olefin containing polymer or a bridged polycyclic olefin containing polymer. An elastomeric piston (24) is slidably attached to the barrel (14) and provides a seal of the chamber. The piston (24) has a parylene coating on an outer surface thereof to reduce the necessary break away force. A plunger (22) is also provided and has a second mating member (42) removably connecting the plunger to a first mating member (44) of the piston. The first mating member (44) has a series of threads having a major diameter and a minor diameter, and the second mating member (42) has a series of threads having a major diameter and a minor diameter. The major and minor diameters of the second mating members (42) is appreciably smaller than the major and minor diameters of the other of the first mating member (44) to provide ease of connection.

  • Cycloolefin blends and method for solvent bonding polyolefins
    Patent number: 6590033
    Abstract: The present invention provides a polymer composition having: a first component selected from homopolymers and copolymers of cyclic olefin containing polymers and bridged polycyclic hydrocarbon containing polymers, the first component being present in an amount from about 1-99% by weight of the composition; and a second component is selected from homopolymers and copolymers of a diene having from 4 to 12 carbons, the second component being present in an amount from about 99% to about 1% by weight of the composition.
