	Wallace Carothers - Wikipedia, the free encyclopedia
		Wallace Hume Carothers (April 27, 1896 - April 29, 1937) was the leader of organic chemistry at DuPont.
		Carothers began his academic career as a faculty member of the University of Illinois at Urbana-Champaign in 1924 where he came to know Roger Adams who was a colleague of E.K. Bolton at DuPont.
		Carothers became head of the chemistry department at Tarkio College in Missouri, a position that he took on while he was still a student.

	History Of Nylon (Site not responding. Last check: 2007-11-06)
		Carothers decided that water, formed as a byproduct in the ester-forming reaction, was hydrolyzing ester groups back to acid and alcohol and that the molecular weight limit reflected an equilibrium between the forward and backward reactions.
		Carothers had established enough of a reputation for himself, both inside and outside Du Pont, that he could continue to work on his scientific studies, in spite of his concerns about what management expected from him.
		Carothers thought that a superpolymer could be prepared without using the still if he used a carefully purified amino acid ester rather than the acid itself.

	Wallace Hume Carothers
		Wallace Carothers was born on April 27th 1896, the eldest of four children, in Burlington, Iowa.
		It was during his time in Illinois that the tormented side of Carothers’ character surfaced when he filled a phial with cyanide, to be carried with him for the rest of his life as an escape route if his fits of depression became too much to bear.
		Carothers’ team was working with over 100 different materials and he identified them by two numbers, indicating the number of carbon atoms in the diacid and diamine.

		The fiber was silk-like in appearance and after Carothers applied the scientific method, he was able to produce the practical fiber known as nylon.
		Carothers epitomized the ideal usage of the scientific method with his ability to systematically break down the problem with the practicality of nylon.
		Secondly, Carothers proposed an explanation for the problem, which identified water as the blockade of polymer formation.

	Nylon - Wikipedia, the free encyclopedia
		Nylon represents a family of synthetic polymers, a thermoplastic material, invented in 1935 by Wallace Carothers at DuPont.
		Nylon 5,10, made from pentamethylene diamine and sebacic acid, was studied by Carothers even before nylon 6,6 and has superior properties, but is more expensive to make.
		But he was not involved in the nylon project during the last year of his life, and committed suicide before the name was coined.

		An American chemist, Wallace Hume Carothers (1896-1937), was enticed in 1928 to leave a prestigious teaching position and instead head a new research group at the DuPont company.
		The next year, Carothers applied for the first of many patents related to these "linear condensation polymers." On February 16, 1937 he was granted patent number 2,071,250.
		Carothers noted in his patent application that the strands of his artificial fiber were "pliable, strong and elastic" and that they resembled silk.

	Proof (Site not responding. Last check: 2007-11-06)
		Carothers liked the theory that rubber and other natural materials were made from macromolecules, but being a good scientist he could not accept it without proof.
		Since the main argument for the colloid theory has been a disbelief that macromolecules could exist, that theory is soon going to end up in the junkyard of ideas along with phlogiston and the giant turtle that was once thought to hold up the earth.

	Wallace Hume Carothers
		Wallace Hume Carothers was born on April 27 1896 in Burlington, Iowa and died on April 29 1937 in Philadelphia, Pa. At the University of Illinois and later at Harvard University, Wallace Carothers performed research and taught organic chemistry.
		Carothers and his co-workers found that by polymerizing (condensation polymerization with the loss of a water molecule) a mixture of adipic acid and 1,6-diaminohexane they could make a plastic (nylon, which is a polyamide).
		Wallace Carothers and his group produced several other nylons that were each a polyamide.
