Polymorphic forms and Polymerization thermodynamics of 2-amino-4-(p-chloroanilino)-6-isopropenyl-1,3,5-triazine by means of DSC.

The second part of this compendium concludes with a collection of phase change enthalpies of organic molecules inclusive of C11–C192 reported over the period 1880–2015. Also included are phase change enthalpies including fusion, vaporization, and sublimation enthalpies for organometallic, ionic liquids, and a few inorganic compounds. Paper I of this compendium, published separately, includes organic compounds from C1 to C10 and describes a group additivity method for evaluating solid, liquid, and gas phase heat capacities as well as temperature adjustments of phase changes. Paper II of this compendium also includes an updated version of a group additivity method for evaluating total phase change entropies which together with the fusion temperature can be useful in estimating total phase change enthalpies. Other uses include application in identifying potential substances that either form liquid or plastic crystals or exhibit additional phase changes such as undetected solid–solid transitions or behave anisotropically in the liquid state.

A series of new isopropenyl-1,3,5-triazines, that is, 2-amino-4-(m-acylaminoanilino)-6-isopropenyl-1,3,5-triazine (AnIT, where "n" means the number of carbon atoms in the acyl group) was synthesized from the reaction of 2-amino-4-(m-aminoanilino)-6-isopropenyl-1,3,5triazine with various acyl chlorides, including acetyl to octadecanoyl. These monomers were polymerized and copolymerized with styrene or methyl methacrylate in dimethyl sulfoxide using AIBN as an initiator, and copolymerization parameters (r 1 , r2 , Q, and e values) of these monomers (M 2) were determined. Glass transition temperatures of the homopolymers of A6IT through AI SIT were around 182°C. The long acyl side-chains of poly(Al6IT) and poly(AISIT) could crystallize and their melting temperatures were-21 °C and 9°C, respectively. The crystallinity of the side-chains decreased with increasing content of styrene or methyl methacrylate in the copolymers.
