Polymeric materials are used from prehistoric times. Polymers are abundant in nature, found in all living systems, and materials such as wood, paper, leather, natural fibers have found extensive use. While natural polymers retain their intrinsic importance, today synthetic materials are mostly used. The first semisynthetic polymers, formed by chemical modification of natural materials, were made in the second half of the nineteenth century. Absolutely synthetic polymers were developed in the twentieth century, most in the period 1950–1970s driven by industry growth. These are the so-called plastics of recent society. The feedstock for polymerization processes is petrochemical, and environmental issues have led to more recent developments of polymers from renewable resources.

Polymer Catalysis has become an independent and thriving branch of chemistry. Extensive development of this field is attributed to the success achieved in synthesis and investigation of so-called functional polymers as well as to success attained inhomogeneous, metal complex catalysis.   The fruitful cooperation of these two directions, namely the fixation of homogeneous catalysts or transition metal compounds on organic polymers, has led to the novel idea of heterogenization of homogeneous metal complex catalysts. Catalysis by polymers is the new intensively developing field of science.

Nanotechnology is among the most recent research regions and it is characterized as building machines at the sub-atomic scale and includes the control of materials on a nuclear (around two-tenths of a nanometer) scale. It is the science and innovation of little things (fewer than 100 nm in size).This clearly incorporates polymer nanotechnology which incorporates microelectronics, polymer-based biomaterials, Nano drug, Nano emulsion particles; polymer bound impetuses, electro spun nano creation and so on. A polymer or copolymer material containing scattered nanoparticles is Nano polymer .The progress from smaller scale to nano-particles prompt change in its physical and in addition compound properties.

These might be of various shape (e.g., platelets, filaments, spheroids), however no less than one measurement must be in the scope of 1– 50 nm. It is considered as the materials of the 21st century because of its surprising property blends and extraordinary outline conceivable outcomes.

Biopolymers are available as coatings for paper rather than the more common petrochemical coatings. Bioplastics are used for disposable items, such as packaging, crockery, cutlery, pots, bowls, and straws. They are also often used for bags, trays, fruit and vegetable containers and blister foils, egg cartons, meat packaging, vegetables, and bottling for soft drinks and dairy products. These plastics are also used in non-disposable applications including mobile phone casings, carpet fibers, insulation car interiors, fuel lines, and plastic piping. New electroactive bioplastics are being developed that can be used to carry electric current. In these areas, the goal is not biodegradability, but to create items from sustainable resources. Medical implants made of PLA (polylactic acid), which dissolve in the body, can save patients a second operation. Compostable mulch films can also be produced from starch polymers and used in agriculture. These films do not have to be collected after use on farm fields.

In Polymer Chemistry, polymerization is a process of reacting monomer molecules together in a chemical reaction to form polymer chains or three-dimensional networks. There are many forms of polymerization and different systems exist to categorize them. In chemical compounds, polymerization occurs via a variety of reaction mechanisms that vary in complexity due to functional groups present in reacting compounds and their inherent steric effects. In more straightforward polymerization, alkenes, which are relatively stable due to sigma bonding between carbon atoms, form polymers through relatively simple radical reactions; in contrast, more complex reactions such as those that involve substitution at the carbonyl group require more complex synthesis due to the way in which reacting molecules polymerize. Alkanes can also be polymerized, but only with the help of strong acids.
