- Abstract
- The objective of the program was to prepare a series of polymeric compositions intended for use as laminating resins which would be flame retardant and would not afford toxic products on oxidative thermal degradation. The polymerization process was the reaction of a suitable diazide with a tertiary diphosphine resulting in the formation of P=N linkages.
