abstract = "Polyolefins (POs) are currently the most widely used engineering plastics due to their
relatively low cost, durability, and ease of processing. A feature such as inertness makes
polyolefins suitable for applications such as food packaging and medical devices. For
the purpose of this study, polyethylene (PE) with good rigidity, hardness, impact
strength, environmental stress cracking resistance, and excellent processability, and
polypropylene (PP), with high fluidity and very good transparency, were selected
polyolefins [1,2]. Knowing that most of the polymer applications are strongly dependent
on the initial state of the products, i.e., their morphology, thermal properties, and
crystallinity, it is possible to obtain a great variety of morphologies and supermolecular
formations by varying different conditions in the preparation process, e.g. cooling
conditions during the crystallization process from the melt.
One of the aims of this work was to compare the results obtained for two different
methods of sample preparation, quenching, and slow cooling. Initial preparation was
performed for selected POs by rapid quenching in ice water and slow air cooling after
compression molding. Further, the prepared samples were characterized by SEM,
WAXD, FTIR, and mechanical measurements.
The obtained results indicated that PP is much more sensitive to the method of sample
preparation than PE, as well as that the initial preparation of samples plays a decisive
role in the final properties of materials for polymeric medical devices.",
