WebCrystallization 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 … Webin when the melt cools. This is how the specific morphology of liquid crystal polymers in the solid state is formed. The morphology is in fact very similar to that of wood (fig. 1) in the LCP matrix, fibers of the same polymer are embedded. These polymers are therefore also described as self reinforcing. A fracture

WebSep 12, 2024 · In polymer chemistry, the width of the distribution of molecular weights is described by the dispersity (Ð, also called, in older texts, the polydispersity or the polydispersity index, PDI). The dispersity of a polymer sample if often between 1 and 2 (although it can be even higher than 2). The closer it is to 1, the narrower the distribution.
