Definition of crystalline polymers
Crystalline state is one of the main forms of polymer condensation, the crystalline polymer composition is called the crystalline region, the disorder region is called amorphous area, the percentage of crystal area is called crystallinity, usually crystal A polymer having a degree of more than 80% is called a crystalline polymer.
General plastic crystal structure is composed of many linear, slender polymer compounds composed of aggregates, according to the degree of regular arrangement of molecules, known as the degree of crystallization (crystallinity), the polymer only part of the individual neatly arranged, so Crystalline resins are usually only partially crystalline. Crystalline polymer polymer regular arrangement of the region known as the crystal area, disorderly area called amorphous zone, the percentage of crystal area called the degree of crystallinity, the degree of polymer crystallinity changes a wide range, generally from 30% 80%. Divided into mass crystallinity and volume crystallinity.
A solid formed by arranging atoms, ions, or molecules in a certain spatial order. Also called crystal. Generally generated by the pure material, with a fixed melting point, optical rotation.
Crystalline polymer polymer regular arrangement of the region known as the crystal area, disorderly area called the amorphous area, the percentage of the crystal area called the degree of crystallinity, usually more than 80% of the polymer is called crystalline polymerization Things.
