1. Observing crystal structure in polymers

New polymers are constantly appearing on the market or in research laboratories, thanks to the invention of new chemical synthesis processes and improved manufacturing processes. They aim to reduce costs, energy consumption and environmental impact, but also to better control the microstructure of polymers, since their mechanical, optical and electrical properties, as well as those of materials in general, are highly dependent on their structure .

Example

in general, the transparency of a polymer can only be observed if it has an amorphous structure; moreover, crystalline isotactic polypropylene outperforms amorphous...
