WebJun 16, 2016 · Once again, when we have segregation, the segregation also goes to the boundaries. Now, the way the crystallization process develops with respect to the polymers, it's a chain folding process. And depending upon the complexity of the polymer that we're dealing with, we can affect the ability of that particular polymer to crystallize. WebDec 15, 2009 · Introduction. A large number of studies concerned with the crystallization kinetics of polymer–polymer mixtures have been reported. One reason for this abundance of information is a basic scientific interest coupled with the many ramifications that are inherent to such systems. There is also a pragmatic interest since physical and …
WebPolymer crystals are usually thin and lamellar when crystallized from either dilute solution or a melt. Lamellar thickness is proportional to the reciprocal of the difference between … WebCrystallization kinetics of polymers and polymer electrolytes is an attractive area for researchers because it has a direct relation to the structure and property of the polymeric materials. The process where an ordered (crystalline) phase is produced from a disordered amorphous phase is referred to as polymer crystallization.
