Polymer with the lowest crystallinity
Did you know?
Webconveniently determine both, the type and the crystallinity of polymer materials, even for inexperienced users. The values are in the range of high (PE 1) and low (PE 2) density PE and isotactic (α-) PP, whereby the differences in crystallinity are influencing the mechanical properties of the polymers. With the latter method, in less than 10 WebWhile crystalline domains are generally needed to achieve high mobility, amorphous domains are necessary to impart stretchability. Recent progresses in the design of high-performance donor–acceptor polymers that exhibit low degrees of energetic disorder, while having a high fraction of amorphous domains, appear promising for polymer …
WebDec 5, 2024 · Abstract. The effects of crystallinity and molecular weight on the ductile-brittle transition of a semi-crystalline polyamide were de-coupled. Low molecular weight organic acid solutions were used to accelerate the molecular weight degradation of polyamide-11 to be faster than with water aging at 120 °C. The mass average molecular weight (Mm ...
