Patent number: 4877917Abstract: A method of cyclization of .alpha.,.omega.-diynes with a transition metal catalyst such as niobium or tantalum salts such as halogen to yield products such as dimers trimers and higher polymers which may have benzo cyclobutene groups, benzocyclopentene groups, benzocyclohexene groups, or none of these, depending on the size of n in the .alpha.,.omega.-diynes of the formula of page 1.Type: GrantFiled: October 17, 1988Date of Patent: October 31, 1989Assignee: University of AkronInventors: Michael F. Farona, Ramji Srinivasan

Patent number: 4599384Abstract: Macromonomers of polymer-dicyclopentadiene and polymer-ethylidenenorbornene are prepared and then terpolymerized with ethylene and propylene. The terpolymer exhibits compatibilization of ethylene-propylene rubber and butyl rubber, and thus is useful as a sealant, roofing material, caulking agent, and the like.Type: GrantFiled: July 23, 1984Date of Patent: July 8, 1986Assignee: The University of AkronInventors: Michael F. Farona, Joseph P. Kennedy

Patent number: 4180692Abstract: A method for carrying out reactions of the Friedel-Crafts type, such as alkylation, acylation, polymerization, sulfonylation and dehydrohalogenation. The reactions are catalyzed by arene-metal tricarbonyl complexes and when the reaction vessel contains aromatic substrates the catalyst may be generated in situ from a metallic hexacarbonyl. The arene-metal tricarbonyl catalyst is more selective than conventionally employed Friedel-Craft catalysts in that it yields generally para isomers with little of the ortho variety and very little if any of the meta variety when the aromatic substrate is reacted with organic halide. It is also possible to form the arene-metal tricarbonyl catalyst outside of the reaction vessel and then proceed by adding it to the vessel containing the substrate and the organic halide as is the case with dehydrohalogenation reactions wherein there are no aromatic rings available, the substrate in that instance being aliphatic.Type: GrantFiled: April 11, 1974Date of Patent: December 25, 1979Assignee: The University of AkronInventors: Michael F. Farona, James F. White
