Article Synopsis
- Self-healing polymers present a new solution to wear and tear in polymer products, addressing damage from mechanical stress and environmental factors.
- A series of high-strength copolymers were developed using acrylamide, acrylic acid, and various metal complexes (Co(II), Ni(II), Cu(II)), and their properties were extensively analyzed through multiple physicochemical techniques.
- Nickel-based metallopolymers showed the highest self-healing efficiency (up to 83%) while retaining impressive tensile strength, demonstrating the potential to enhance mechanical properties through different metal ions.

Ethylene/propylene (E/P) and ethylene/propylene/5-ethylidene-2-norbornene (E/P/ENB) copolymers were obtained on -Et(2-MeInd)ZrMe activated by a number of isobutylaluminium aryloxides: (2,6-BuPhO-)AlBu (1-DTBP) (2,6-Bu,4-Me-PhO-)AlBu (1-BHT), (2,4,6-BuPhO-)AlBu (1-TTBP), (2,6-Bu,4-Me-PhO-)AlBu (2-BHT), (2,6-BuPhO-)2AlBu (2-DTBP), [(2-Me,6-Bu-CHO)AlBu] (1-MTBP), [(2,6-Ph-PhO)AlBu] (1-DPP). This study shows how the structure of an activator influences catalytic activity and polymer properties, such as the copolymer composition, molecular weight characteristics, and thermophysical and mechanical properties. It has been shown that both the introduction of a bulky substituent in the para-position of the aryloxy group and the additional aryloxy group in the structure of an activator lead to a significant decrease in activity of the catalytic system in all studied copolymerization processes.

Methods: Seventeen hospital and outpatient medical centres from 13 regions of the Pilot Project. Baseline questionnaires assessed the involvement of multidisciplinary teams, staffing, and the equipment in healthcare facilities.
Background: Rehabilitation measures are crucial for maintaining clinical benefits of coronary artery bypass grafting (CABG) surgery. We evaluated the clinical efficacy of a medical centre- and home-based cardiac rehabilitation (CR) for patients after CABG in an out-patient setting.
Methods: The study included 36 male patients 3-8 weeks after CABG that were randomly assigned to either study or control group.
