|Abstract||The ring-opening metathesis copolymerizations of deltacyclene, substituted deltacyclene, and norbornene was achieved using RuCl3, ReCl5, and molybdenum alkylidene catalysts. The reaction conditions employed are similar to those used previously in the syntheses of homopolymers. The low conversion copolymerization of deltacyclene and norbornene showed that deltacyclene is more reactive than norbornene by a factor of 2.4. The characterization and physical properties of these copolymers were determined using NMR, GPC, Tg, and viscosity measurements.|
