Morphology study of progesterone polymorphs prepared by polymer-induced heteronucleation (PIHn).

In this article, morphology of progesterone polymorphs prepared by polymer-induced heteronucleation (PIHn) technique was studied. Hydroxypropyl methylcellulose(HPMC), such as dextran T-500 and gelatin G-9382, polyisoprene (PI), and acrylonitrile/butadiene copolymer (NBR) were used as substrates. The crystallizations were performed by solvent evaporation at room temperature from 0.
