14257 IUPAC Gold Book - dominant lamellae 10.1351/goldbook.14257 14257 current 1 Lamellar crystals radiating from the center of the spherulite which, by splaying, constitute the initial skeleton of the spherulite. Crystallization of dominant lamellae is largely associated with primary crystallization. In the isothermal crystallization of crystalline polymers there is normally a single population of dominant lamellae, characterized by a single thickness. The thickness and perfection of dominant lamellae is greater than for subsidiary lamellae, especially in non-isothermal crystallization. isothermal crystallization https://goldbook.iupac.org//terms/view/14266 non-isothermal crystallization https://goldbook.iupac.org//terms/view/14267 subsidiary lamellae https://goldbook.iupac.org//terms/view/14258 PAC, 2011, 83, 1831.
