The eight most common types of synthetic organic polymers, which are commonly found in households are: Low-density polyethylene (LDPE) High-density polyethylene (HDPE) Polypropylene (PP) polyethylene (PP) Polyvinyl chloride (PVC) Polystyrene (PS) formaldehyde. Nylon, nylon 6, nylon 6,6; Teflon (Polytetrafluoroethylene) Thermoplastic ...
However, polymer chemistry is typically related to synthetic and organic compositions. Synthetic polymers are ubiquitous in commercial materials and products in everyday use, such as plastics , and rubbers , and are major components of composite materials.
Most plastics contain organic polymers. [12] The vast majority of these polymers are formed from chains of carbon atoms, with or without the attachment of oxygen, nitrogen or sulfur atoms. These chains comprise many repeating units formed from monomers. Each polymer chain consists of several thousand repeating units.

In the oil and gas industry, polyacrylamide derivatives (especially co-polymers) have a substantial effect on production by enhanced oil recovery by viscosity enhancement. High viscosity aqueous solutions can be generated with low concentrations of polyacrylamide polymers, which are injected to improve the economics of conventional water-flooding.
A polymer (/ ˈ p ɒ l ɪ m ər / [4] [5]) is a substance or material that consists of very large molecules, or macromolecules, that are constituted by many repeating subunits derived from one or more species of monomers. [6] Due to their broad spectrum of properties, [7] both synthetic and natural polymers play essential and ubiquitous roles ...
Low molecular weight poly-alpha-olefins are useful as synthetic lubricants such as synthetic motor oils for vehicles and can be used over a wide temperature range. [ 8 ] [ 10 ] Even polyethylenes copolymerized with a small amount of alpha-olefins (such as 1-hexene , 1-octene , or longer) are more flexible than simple straight-chain high-density ...
Polystyrene (PS) / ˌ p ɒ l i ˈ s t aɪ r iː n / is a synthetic polymer made from monomers of the aromatic hydrocarbon styrene. [5] Polystyrene can be solid or foamed . General-purpose polystyrene is clear, hard, and brittle.
