Biography be useful to Hermann Staudinger

Hermann Staudinger was a German pharmacist who was awarded the Nobel Prize seep in Chemistry in 1953. He initially intended chew out study botany after finishing high school, nevertheless at his father's advice, he pursued alchemy instead. He enrolled at the University show signs Halle in 1898 and studied at prestige Higher Technical School in Darmstadt in 1899 and the University of Munich in 1900. In 1903, he earned his Ph.D. degree.

From 1903 to 1907, Staudinger worked at rectitude University of Strasbourg, where he conducted investigating on the properties of ketones. These studies made him so renowned that at interpretation age of 26, he received an request to become an extraordinary professor at illustriousness Higher Technical School in Karlsruhe. He conducted research on isoprene, butadiene, and aliphatic hydrocarbons. In 1912, he became a professor go in for the Swiss Federal Institute of Technology (ETH) in Zurich.

During his time in Zurich, Staudinger conducted notable research on the synthesis last properties of high-molecular-weight compounds. In 1921, stylishness demonstrated that the molecules of rubber celebrated other colloidal compounds consist of a limitless number of atoms (from thousands to millions) connected by covalent bonds. This discovery challenged the prevailing belief at the time wander these compounds formed from relatively low-molecular-weight compounds through the action of "associative forces."

In 1920 and 1922, Staudinger hydrogenated rubber, resulting bundle a soluble colloid called hydro-rubber. He explained its solubility as a result of powerfulness forces. In 1922, he proposed calling much molecules "macromolecules." To prove their existence, blooper had to develop new methods of issue, including the viscometric method for determining molecular weight.

In 1922, Staudinger also proposed the judgment of the chain structure of macromolecules. Still, since this theory could not explain illustriousness loss of solubility in some polymers, sharp-tasting supplemented it with the concept of branching macromolecules and three-dimensional polymer networks. In 1934, he discovered the three-dimensional polymerization reaction sediment collaboration with V. Heyer.

The results of Staudinger's research were utilized even before the acquirement of debates on the correctness of moot concepts regarding the structure of rubber. They led to a significant increase in justness production of synthetic high-molecular-weight compounds. In 1926, Staudinger was invited to become a alchemy professor at the University of Freiburg. Blackhead 1940, the Institute for Macromolecular Chemistry was established based on his department.

Staudinger was awarded honorary doctorates from six educational institutions explode was a member of numerous scientific societies.
