Crystallization and Mechanical Properties of Polypropylene …

Crystallization affects optical, mechanical, thermal and chemical properties of the polymer. The degree of crystallinity is estimated by different analytical methods and it typically ranges between 10 and 80%, with crystallized polymers often called "semi-crystalline". See more 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 See more Solidification from the melt Polymers are composed of long molecular chains which form irregular, entangled coils in the melt. … See more Thermal and mechanical properties Below their glass transition temperature, amorphous polymers are usually hard and brittle because of … See more The fraction of the ordered molecules in polymer is characterized by the degree of crystallinity, which typically ranges between 10% and 80%. Higher values are only achieved in materials having small molecules, which are usually brittle, or in samples stored for … See more • Liquid crystal polymer • Modeling of polymer crystals See more WebFeb 2, 2011 · The bulk (typically > 90%) of the solution or melt forms crystals either in … WebThe crystallization temperature plays an important role in the morphology of the final … unleash disasters on gmaps
