SummaryThe solution polymerization of phosphonitrilic chloride trimer has been studied by using 50% by weight monomer in Chlorobenzene. Polymerization reactions were conducted at temperatures between 198° and 240°C, and reaction times ranged from 12 to 96 h. Mostly soluble polymer was obtained up to a conversion of 30%. insoluble product was detected only above 240°C and 72 h. of reaction time. Polymers were characterised by intrinsic viscosity and weight average molecular weight, Mw, by light scattering (Zimm plot).
