Polycyanurate networks of different architecture were synthesized using different curing cycles. Networks with a variable extent of reaction were obtained; the small variation of the cyanate conversion (0.8 to 1) corresponds to a large variation of glass transition temperature (150-290ΠC) and crossl
The empirical form for the dependence, Tg(n) = Tg(co) (1 + a / n ) , of the glass transition temperature Tg on the average number n of repeat units between crosslinks, is generalized for randomly crosslinked high polymers. The new form, TJn) is based on a correlation study of data for 77 samples of
