  • Method for coating of biotissue substrates
    Patent number: 6875461
    Abstract: In a method for coating a calcium phosphate compound on a biotissue substrate or, particularly, in case the biotissue substrate is biotissue, there is provided a method for coating of biotissue substrate where the method causes no damage thereto, is very mild even to biotissues which are other than the biotissue to be coated and is able to form a uniform coat. A method for coating a calcium phosphate compound on a biotissue substrate by an alternate soaking method which is characterized in that, as the soaking solutions, there are used a solution containing a water-soluble calcium salt and borate and/or L-histidine and a phosphate solution.

  • Process for producing a water-soluble vinyl polymer
    Patent number: 4376021
    Abstract: A water-soluble vinyl polymer is produced by polymerizing a water-soluble vinyl monomer in the presence of a catalyst or under the action of ultraviolet rays to prepare a polymer having a degree of polymerization of at least 95%, adjusting the water content of the system containing said polymer to be within the range of from 15 to 30%, and irradiating said system with ionizing radiation.
