Synthetic high polymers have become an integral part of modern material science, influencing industries such as healthcare, construction, packaging, and electronics. This paper explores the classification, properties, and applications of synthetic high polymers while providing insights into future trends and innovations [1].

Polymers, large macromolecules composed of repeating structural units, can be broadly classified into natural and synthetic polymers [2]. Synthetic high polymers, engineered through controlled polymerization techniques, exhibit tailored properties suitable for diverse applications. This paper examines the fundamental aspects of synthetic high polymers, their advancements, and their role in shaping technological progress [3]. Synthetic high polymers have revolutionized industries ranging from healthcare and automotive to textiles and packaging. These long-chain macromolecules primarily composed of repeating monomer units, exhibit remarkable mechanical, thermal, and chemical properties, making them indispensable in modern applications [4]. The development of synthetic polymers gained significant momentum in the early 20th century, with landmark discoveries such as Bakelite, nylon, and polyethylene. Today, the polymer industry continues to evolve, integrating advanced research in nanotechnology, sustainability, and material science to create next-generation materials with enhanced functionality and environmental benefits. The versatility of synthetic high polymers lies in their ability to be engineered for specific purposes [5]. Polymers such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), and polyethylene terephthalate (PET) have widespread applications due to their durability, lightweight nature, and cost-effectiveness. In contrast, high-performance polymers such as polyether ether ketone (PEEK) and polytetrafluoroethylene (PTFE) cater to specialized fields such as aerospace, medical implants, and electronics. The study of synthetic polymers not only encompasses their structural and functional properties but also examines their production techniques, degradation mechanisms, and recyclability [6].

With increasing concerns about environmental sustainability, the polymer industry is witnessing a paradigm shift towards eco-friendly and biodegradable alternatives [7]. Research in biopolymers, recyclable plastics, and polymer composites aims to reduce dependency on fossil-fuel-derived materials and minimize plastic waste accumulation. Furthermore, innovations such as self-healing polymers, shape-memory materials, and smart polymers are paving the way for futuristic applications in medicine, robotics, and energy storage [8]. As industries strive to balance functionality with sustainability, understanding the properties, applications, and future trends of synthetic high polymers is critical to driving innovation and addressing global challenges.

Classification of synthetic high polymers

Synthetic high polymers can be classified based on their synthesis process, structure, and physical properties. The major categories include:
