Catalyst and fluorinated-monomer combinations were screened for activity in homopolymerization and copolymerization. Copolymerizations of fluorinated dienes with butadiene or ethylene and butadiene were studied using both coordination and ionic catalysts. Preliminary studies were made of the relation of feed ratio to combined monomer ratio in some of these polymerizations. The additions of sulfenyl chlorides and nitrosyl fluoride-hydrogen fluoride complex NOF . 3HF to cis-polybutadiene were studied.
