Few synthetic polymers are entirely crystalline. citation The crystallinity of polymers is characterized by their degree of crystallinity, ranging from zero for a completely non-crystalline polymer to one for a theoretical completely crystalline polymer. Source: Internet
He discovered that these polymers are crystalline materials and ascribed their crystallinity to a special feature of the polymer structure called stereoregularity. Source: Internet
Polymers display varying degrees of crystallinity, and many are completely non-crystalline. Source: Internet
Synthetic polymers may consist of both crystalline and amorphous regions; the degree of crystallinity may be expressed in terms of a weight fraction or volume fraction of crystalline material. Source: Internet
