Patent number: 5036115Abstract: Melanin is used as the absorbing pigment for radiation protective eyeware. Thus, a melanin-plastic copolymer was formed by adding a catalyst (benzoyl peroxide) to the liquid monomer, diethylene glycol bis allyl carbonate (CR-39), which contained dissolved catechol (a melanin precursor); the solution was heated for one day at 50 degrees celsius and an additional two days at 65 degrees celsius and yielded an optically transparent solid plastic with amber color and with an optical absorption spectrum very close to that associated with melanin.Type: GrantFiled: March 19, 1990Date of Patent: July 30, 1991Assignee: Photoprotective Technologies, Inc.Inventor: James M. Gallas

Patent number: 5004560Abstract: Basic polypyrrylenemethines, and salts thereof, having conjugated double bonds and constructed from optionally substituted five-membered heterocyclic rings containing nitrogen, as the only hetero atom in the ring are disclosed, with the five-membered rings, in each case, being bonded to one another in pairs via an optionally substituted carbon atom as a bridging member. The polymer compositions of the invention contain at least five of these five-membered rings and 0 to 50%, relative to the weight of these polymers, of dopants and/or being electrochemically doped. A process for the preparation of the claimed compositions is further disclosed. The polymer compositions of the invention have electroconducting and semi-conducting properties and are useful, for example, in batteries, circuits and switches, if appropriately used in conjunction with other polymers. In addition, the compounds of the invention can also be employed as absorbents for heavy metals and as catalysts.Type: GrantFiled: March 17, 1988Date of Patent: April 2, 1991Assignee: Wacker-Chemie GmbHInventors: Hermann Braunling, Richard Becker
