Abstract
Several techniques were used to characterize the polymorphism in polyalcohol 2-amino-2-methyl-1, 3 propanediol, (CH2OH)2CH3C NH2, which exhibits a solid crystalline plastic phase. Three equilibrium and two nonequilibrium states were determined in the temperature range from 0 to 150 °. One of the nonequilibrium states reveals characteristics of a glassy crystal, a frozen state from the plastic phase. Although different results agree with this affirmation, further analysis is needed to verify the glassy crystal definition of Suga and Seki [68Ada].
