Polymers timeline.

Nitrocellulose (also known as cellulose nitrate, flash paper, flash cotton, guncotton, and flash string) is a highly flammable compound formed by nitrating cellulose through exposure to nitric acid or another powerful nitrating agent. When used as a propellant or low-order explosive.it was originally known as guncotton.

Celluloids are a class of compounds created from nitrocellulose and camphor, with added dyes and other agents. Generally considered the first thermoplastic, it was first created as Parkesine in 1856[1] and as Xylonite in 1869, before being registered as Celluloid in 1870. Celluloid is easily molded and shaped, and it was first widely used as an ivory replacement.

Bakelite or polyoxybenzylmethylenglycolanhydride was the first plastic made from synthetic components. It is a thermosetting phenol formaldehyde resin, formed from a condensation reaction of phenol with formaldehyde. It was developed by the Belgian-American chemist Leo Baekeland in Yonkers, New York, in 1907.

Rayon is a manufactured fiber made from natural sources such as wood and agricultural products that are regenerated as cellulose fiber. The many types and grades of rayon can imitate the feel and texture of natural fibers such as silk, wool, cotton, and linen. The types that resemble silk are often called artificial silk.

Cellophane is a thin, transparent sheet made of regenerated cellulose. Its low permeability to air, oils, greases, bacteria, and water makes it useful for food packaging. Cellophane is highly permeable to water vapour, but may be coated with nitrocellulose lacquer to prevent this.

PVC comes in two basic forms: rigid (sometimes abbreviated as RPVC) and flexible. The rigid form of PVC is used in construction for pipe and in profile applications such as doors and windows. It is also used in making bottles, non-food packaging, food-covering sheets,[8] and cards (such as bank or membership cards).

Neoprene (also polychloroprene or pc-rubber) is a family of synthetic rubbers that are produced by polymerization of chloroprene. Neoprene exhibits good chemical stability and maintains flexibility over a wide temperature range. Neoprene is sold either as solid rubber or in latex form and is used in a wide variety of applications, such as laptop sleeves, orthopaedic braces, electrical insulation, liquid and sheet applied elastomeric membranes or flashings, and automotive fan belts.

Nylon (Spanish spelling of the trade name Nylon, registered trademark) is a synthetic polymer that belongs to the polyamide group. Nylon is an elastic and resistant textile fiber, the moth does not attack it, does not require ironing and is used in the manufacture of socks, fabrics and knitted fabrics, also bristles and sedans. Molded nylon is used as a hard material in the manufacture of various utensils, such as brush handles, combs, etc.

Polyethylene or polythene (abbreviated PE; IUPAC name polyethene or poly(methylene)) is the most common plastic. As of 2017, over 100 million tonnes of polyethylene resins are produced annually, accounting for 34% of the total plastics market.Its primary use is in packaging (plastic bags, plastic films, geomembranes, containers including bottles, etc.). Many kinds of polyethylene are known, with most having the chemical formula (C2H4)n.

Polytetrafluoroethylene (PTFE) (better known as Teflon) is a polymer similar to polyethylene, in which hydrogen atoms have been replaced by fluorine atoms. The chemical formula of the monomer, tetrafluoroethene, is CF2 = CF2. The polymer formula is shown in the figure.

Regardless of whether or not these containers correspond to those marketed under the Tupperware brand, 1 in Spanish the taper apócope (plural: taper) has been popularized as a Spanish adaptation of the tupper2 foreignism to designate this type of airtight containers. The Fundéu notes that the term taper is included in reference lexicographical works of the Spanish language (such as the Key Dictionary and the current Spanish Dictionary by Manuel Seco, Gabino Ramos and Olimpia Andrés).

Kevlar or polyparaphenylene terephthalamide is a polyamide first synthesized in 1965 by Polish-American chemistry Stephanie Kwolek (1923-2014), who worked for DuPont. Obtaining Kevlar fibers was complicated, highlighting the contribution of Herbert Blades

Polyester amides constituted by ester units mainly comprising benzenedicarboxylic acid and 1,4-butanediol and amido units comprising dodecanamido and/or undecanamido units, with the weight ratio of said ester units to said amido units being 5 to 95 : 95 to 5, which have excellent mechanical strength, transparency, oil resistance, adhesiveness, and heat-sensitive characteristics, a process for their preparation, and an adhesive for fibers and metals comprising said polyester amides.
