Ionomerní

Ionomerní is a term derived from the Czech language, essentially meaning "ionomer-like" or pertaining to ionomers. Ionomers are a class of polymers that contain ionic functional groups. These ionic groups, when present in the polymer chain, create ion pairs. The presence of these ionic interactions significantly alters the physical and chemical properties of the polymer compared to its non-ionic analog.

The ionic groups are typically created by the neutralization of acidic functional groups within the polymer backbone with metal cations. Common examples of ionomers include ethylene-acrylic acid copolymers neutralized with metal ions like sodium, zinc, or magnesium. These ionic clusters act as crosslinking points, leading to increased tensile strength, improved elasticity, and enhanced chemical resistance.

The unique properties of ionomers make them suitable for a wide range of applications. They are found in golf ball covers due to their durability and resilience. They are also used in packaging films, adhesives, automotive parts, and membranes for various separation processes. The specific properties can be fine-tuned by adjusting the type and concentration of ionic groups and the nature of the metal cation used for neutralization. The term "ionomerní" would therefore be used to describe materials or phenomena exhibiting characteristics associated with these ionomer polymers.
