Petrochemicals Historical timeline- Part 7

Early 1950s Polypropylene discoveries were made in different places because of improved knowledge sharing but this led to nine different teams claiming

to have invented it. Patent litigation was finally resolved in 1989. American chemists Paul Hogan and Robert Banks, working for Phillips Petroleum, are generally credited as the inventors.

1955 South Africa started making its own synthetic fuels using the Fischer-Tropsch method because of limited oil imports with the trade sanctions under the apartheid regime.

1960s Work conducted on water conservation for soils in the US led to the development of a resin in the form of an acrylic gel which were then developed into super-absorbent fibres.Commercial production began in Japan in 1978 and in 1980, super-absorbent polymer was used in baby diaper production.

1960s First synthetic oils are developed with Mobil Oil and AMSOIL leading the field. The synthetics contain additives such as polyalphaolefins

derived from olefins. Introduced commercially in the 1970s to the automotive market.

1963 Australian chemists start work on conducting substances for computer screen shields, windows that can exclude sunlight and photographic film.

1965 Kevlar was invented at DuPont as a result of research involving high performance chemical compounds. It is used in bullet-proof vests, underwater cables, space vehicles, brake linings, skis,building materials, parachutes, boats and skis.
