WebJun 20, 2024 · Measuring crystallinity of polymers can be done in several ways depending on the information or equipment available to us. The percentage crystallinity of a polymer can be found through an... Crystallization of polymers is a process associated with partial alignment of their molecular chains. These chains fold together and form ordered regions called lamellae, which compose larger spheroidal structures named spherulites. Polymers can crystallize upon cooling from melting, mechanical stretching or solvent evaporation. Crystallization affects optical, mechanical, thermal and chemical properties of the polymer. The degree of crystallinity is estimated by different analy… WebThese broad features are called a halo hump or amorphous halo. Integration Method analysis. The integration method uses a straight background line and compares the area under the entire curve with the area under the crystalline peaks using the following equation. %Crystallinity = [ (area under the crystalline peaks)/ (area under all peaks)] *100. ralph fiennes christian bale
