Julian W. Hill

Born 4 Sep 1904; died 28 Jan 1996 at age 91.Julian Werner Hill was an American chemist was a U.S. research chemist who discovered cold drawing, a technique of strengthening polymer fibers by stretching. Julian Hill and Wallace Carothers had been building long polymer chains by a reaction of a carboxylic acid with an alcohol to give an ester in a device called a molecular still. While removing a sample of the resultant product from the still, Hill observed that the molten polymer could be drawn into fibers. He then made an important and unexpected discovery - that after being cooled, these pliable filaments could be stretched or "cold drawn" to form very strong fibers. Further tests on the sample showed that it had a molecular weight of over 12,000, far higher than any previous polymer.
