WebLiquid crystal polymers (LCPs) are polymers with the property of liquid crystal, usually containing aromatic rings as mesogens. Despite uncrosslinked LCPs, polymeric … Webquantifying the heat associated with melting (fusion) of the polymer. This heat is reported as Percent Crystallinity by normalizing the observed heat of fusion to that of a 100 % crystalline sample of the same polymer. As authentic samples of 100 % crystalline polymer are rare, literature values are often used for this value (1,2). EXPERIMENTAL soil survey of clinton county il

Polymer Chemistry: Crystallization Tendency

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 … See more Solidification from the melt Polymers are composed of long molecular chains which form irregular, entangled coils in the melt. Some polymers retain such a disordered structure upon freezing and readily convert … See more • Liquid crystal polymer • Modeling of polymer crystals 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 … See more Thermal and mechanical properties Below their glass transition temperature, amorphous polymers are usually hard and brittle because of the low mobility of their molecules. … See more WebThe crystallization behavior of polymer resin is important to know. For polymer processors, it helps to optimize the processing conditions like mold temperature and holding time. DSC is traditionally used to study the thermophysical properties of polymers.
