“…In a series of studies on the polymerization thermodynamics of isopropenyl-l,3,5-triazines, we observed that the ceiling temperature and the heat of polymerization depend on the steric effects and electronic effects of the substituents. [8][9][10][11][12][13] Isopropenyltriazines are suitable for systematic investigation on the thermodynamics of polymerization, because 0024-9297/91/2224-4733$02.50/0 the monomers can be easily polymerized without an initiator after melting and various substituents can readily be introduced to them. In order to obtain the information about the steric effects on the thermodynamics of polymerization more clearly, the thermal polymerization of 2-amino-4-(N-alkylanilino)-6-isopropenyl-l,3,5-triazinesis investigated by means of DSC.…”
