Jerome Roteman has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Epoxy resin photoresist with iodoform and bismuth triphenyl
    Patent number: 3988152
    Abstract: Photopolymerizable compositions and processes for photopolymerizing such compositions are provided, said process comprising admixing with said epoxides, photosensitive organohalogen compounds in combination with an organometallic compound and thereafter applying energy to the resulting mixture. The organohalogens decompose to liberate an active catalyst which then serves to initiate polymerization of the epoxide material. The organometallic compound functions synergistically with the organohalogen to enhance the film forming properties of the resulting polymer and or sensitivity of the polymerizable system.
    Type: Grant
    Filed: February 26, 1975
    Date of Patent: October 26, 1976
    Assignee: American Can Company
    Inventor: Jerome Roteman
