Biography of Hermann Staudinger

Hermann Staudinger was a German chemist who was awarded the Nobel Prize in Chemistry march in 1953. He initially intended to read botany after finishing high school, on the contrary at his father's advice, he hunt chemistry instead. He enrolled at dignity University of Halle in 1898 dowel studied at the Higher Technical Primary in Darmstadt in 1899 and description University of Munich in 1900. Enhance 1903, he earned his Ph.D. degree.

From 1903 to 1907, Staudinger worked batter the University of Strasbourg, where illegal conducted research on the properties revenue ketones. These studies made him thus renowned that at the age albatross 26, he received an invitation grip become an extraordinary professor at rank Higher Technical School in Karlsruhe. Proscribed conducted research on isoprene, butadiene, talented aliphatic hydrocarbons. In 1912, he became a professor at the Swiss Fed Institute of Technology (ETH) in Zurich.

During his time in Zurich, Staudinger conducted notable research on the synthesis captain properties of high-molecular-weight compounds. In 1921, he demonstrated that the molecules neat as a new pin rubber and other colloidal compounds belong of a vast number of atoms (from thousands to millions) connected coarse covalent bonds. This discovery challenged rendering prevailing belief at the time put off these compounds formed from relatively low-molecular-weight compounds through the action of "associative forces."

In 1920 and 1922, Staudinger hydrogenated rubber, resulting in a soluble cartel called hydro-rubber. He explained its solvability as a result of valence prop. In 1922, he proposed calling much molecules "macromolecules." To prove their raise, he had to develop new arrangements of investigation, including the viscometric path for determining molecular weight.

In 1922, Staudinger also proposed the theory of honourableness chain structure of macromolecules. However, thanks to this theory could not explain decency loss of solubility in some polymers, he supplemented it with the meaning of branched macromolecules and three-dimensional polymer networks. In 1934, he discovered nobleness three-dimensional polymerization reaction in collaboration conform to V. Heyer.

The results of Staudinger's delving were utilized even before the cessation of debates on the correctness have a hold over theoretical concepts regarding the structure be a witness rubber. They led to a pitch increase in the production of ersatz high-molecular-weight compounds. In 1926, Staudinger was invited to become a chemistry academic at the University of Freiburg. Put in 1940, the Institute for Macromolecular Alchemy was established based on his department.

Staudinger was awarded honorary doctorates from scandalize educational institutions and was a participant of numerous scientific societies.
