History of Polymers for Students

This document provides a history of polymers and plastics from ancient times to the present. It describes how ancient peoples used naturally occurring plastics like rubber. In the 1500s, British explorers discovered that the Mayans used rubber balls. In 1839, Charles Goodyear discovered vulcanization which made rubber more durable. In the early 20th century, the first synthetic plastics like Bakelite and celluloid were developed. Major advances in polymer science occurred in the 1920s and research accelerated. Nylon was developed in 1938 and polyethylene in 1941, which are now widely used. Modern high temperature polymers emerged in the 1970s and materials like Kevlar were invented, finding applications in bulletproof vests. Today,

A polymer is simply a very large molecule made up of many smaller units joined
together, generally end to end, to create a long chain. Many ancient peoples worldwide used
naturally occurring plastics for a range of decorative and functional purposes. These included
materials such as bitumen, amber, waxes, lac and rubbers and especially horns of different types
were moulded or shaped, some being filled and used as coatings. In the last millennium more
systematic developments and commercial applications led to increasingly rapid changes.

YEAR DESCRIPTION
1500’s British explorers discover the ancient
Mayan Civilization in Central America. The
Mayans are assumed to be among the first to
find an application for polymers, as their
children were found with balls made from local
rubber trees.
1839 Charles Goodyear discovers
vulcanization, by combusting natural rubber
with sulfur and heating it to 270oF. Vulcanized
rubber is a polymeric substance that is much
more durable than its natural commuter. Its
most common use in modern times is in
automobile tires.
1907 The oldest recorded synthetic plastic is
fabricated by Leo Bakeland. Bakelite’s
hardness and high heat resistivity made it an
excellent choice as an electrical insulator.
1917 X-ray crystallography is invented as a
method of analyzing crystal structures. Eight
years later, this method is used by M. Polanyi
to discover the chemical structure of cellulose.
This establishes the fact that polymer unit cells
contain sections of long chain molecules rather
than small molecular species.
1920 Staudinger published his classic paper
entitled “Uber Polymerization”. Publication of
this paper heralded a decade of intense
research and presented to the world the
development of modern polymer theory.
1927 Large scale production of vinyl-chloride
resins begins. This polymeric compound
continues to be widely used today to make
plumbing (PVC) pipe, Euttery tile, and bottles.
1930 Polystyrene is invented. This polymeric
material is used in videocassettes and other
packaging. Expanded polystyrene (commonly
called Styrofoam) is used in cups, packaging,
and thermally insulated containers.
1938 Wallace Carothers of the Dupont
company produces another well-known
polymeric product, nylon. Nylon is a common
material used today for such applications as
popes and clothes.
1941 Polyethylene is developed. Billions of
pounds of both high and low density versions
of this material are produced annually for
everything from packaging film to piping to
toys.
1970 James Economy develops one of the
pioneer moldable high temperature polymers
(Ekonol). This polymeric material paved the
way for the development of liquid crystal
polymers one year later. Ekonol’s most
common applications occur in electronic
devices and aircraft engines.
1971 S.Kwolek, who has been awarded more
than 37 patents in polymer science, develops
Kevlar. Kevlar is a high strength material that
can withstand temperatures up to 300oC, and is
used in applications such as bullet proof vests,
and fire proof garments for firefighting and
auto racing.
1976 – present The polymer or plastics industry
outstripped steel as the nation’s most widely
used material per unit volume. In modern era,
plastic is being used more than steel, aluminum
and copper combined.
