  • Method of coring crustal core sample, and antimicrobial polymeric gel and gel material used in the method
    Patent number: 6695076
    Abstract: A method of taking a crustal core sample, wherein the crustal core sample is obtained in a state coated with an antimicrobial polymeric gel formed of a polymer obtained by polymerizing an antimicrobial monomer, preferably a quaternary ammonium salt compound. The polymer preferably contains a component derived from the antimicrobial monomer in a proportion of 1 to 10 mol%.
    Type: Grant
