Abstract : The (C6H5O)2PN-(4-C2H5C6H4O)2PN)n elastomer was prepared in quantities totaling 5 kg for evaluation as a flame-retardant thermal insulation. The copolymers were characterized by low chlorine content (<0.1%), intrinsic viscosities of 1.7 - 2.8 dl/g (benzene 30C) and C6H5O/4-C2H5C6H4O substituent ratios of 1:1. (Author)
