WebNov 6, 2024 · Therefore, the exothermal peaks derived from the cold crystallization behavior belongs to ITIC in the respective polymer blends and this corresponds to ITIC's cold crystallization temperature (T CC). 33, 46 It is interesting to note that the more crystalline PffBT4T-2OD blend with ITIC resulted in a sharper peak with the lowest T CC … WebWeir et al. [3] conducted a study to analyze silicone rubber at low temperatures and found that a cold crystallization occurs between -60°C and -67°C and the degree of that crystallization depends on the rate at which the part is cooled. The higher the cooling rate, the lower the crystallinity after the cooling [4].

Crystallization affects optical, mechanical, thermal and chemical properties of the polymer. The degree of crystallinity is estimated by different analytical methods and it typically ranges between 10 and 80%, with crystallized polymers often called "semi-crystalline". See more 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 See more Solidification from the melt Polymers are composed of long molecular chains which form irregular, entangled coils in the melt. … See more Thermal and mechanical properties Below their glass transition temperature, amorphous polymers are usually hard and brittle because of … See more The fraction of the ordered molecules in polymer is characterized by the degree of crystallinity, which typically ranges between 10% and 80%.
