Newport (Welsh: Casnewydd) is a city and principal area in Wales, in the United Kingdom. Standing on the banks of the River Usk, located roughly between Cardiff and Bristol, it is the cultural capital [1] and largest urban area in the historic county of Monmouthshire and governed by the unitary Newport City Council. The population of Newport is 140,100, making it the third most populous city in Wales. According to Census 2001 data the population of the core built-up area was 116,143.[1] The name 'Newport' derives from the fact that Caerleon was the 'old port' on the river Usk, but as ships became bigger, they could no longer navigate the river to Caerleon so a new port/dock was built near where the Riverfront Arts Centre stands today. The Welsh language name for the city, Casnewydd-ar-Wysg (IPA: [kasˈnɛwɪð ar ˈwɪsk]) means 'New castle-on-Usk' (this is a shortened version of Castell Newydd ar Wysg)[citation needed]. This refers to the twelfth-century castle ruins near the city centre. The original Newport Castle was a small Motte-and-bailey castle in the park opposite St. Woolos Cathedral. It was buried in rubble excavated from the railway tunnels that were dug under Stow Hill in the 1840s and no part of it is currently visible.[2] Newport also has the Latin name Novus Burgus, meaning new borough or new town. It is sometimes labelled Newport-on-Usk on old maps.[3] The city's importance as a trading port in the Middle Ages was emphasised when a 15th century ship, referred to locally as the Newport ship, was uncovered from the bank of the Usk in 2002, during the construction of the Riverfront Arts Centre. The city is home to the Celtic Manor Resort, a five-star conference resort and home of the Celtic Manor Wales Open, the annual European Tour golf tournament. The resort is also venue for the 2010 Ryder Cup. Contents [hide]

History Polyvinyl chloride was accidentally discovered on at least two different occasions in the 19th century, first in 1835 by Henri Victor Regnault and in 1872 by Eugen Baumann. On both occasions, the polymer appeared as a white solid inside flasks of vinyl chloride that had been left exposed to sunlight. In the early 20th century, the Russian chemist Ivan Ostromislensky and Fritz Klatte of the German chemical company Griesheim-Elektron both attempted to use PVC (polyvinyl chloride) in commercial products, but difficulties in processing the rigid, sometimes brittle polymer blocked their efforts. In 1926, Waldo Semon and the B.F. Goodrich Company developed a method to plasticize PVC by blending it with various additives. The result was a more flexible and more easily-processed material that soon achieved widespread commercial use.
