...from discouraged, he lectured on his experiments. One day a scout for the du Pont Co. heard him, immediately enlisted his aid. Du Pont was seeking a means of producing synthetic rubber, thought Father Nieuwiand might be on the right track. Two years later Father Nieuwland's divinylacetylene was treated with a vulcanizing agent and there was produced a material somewhat resembling rubber. It bounced...
...Jackson Laboratories and in Father Nieuwland's laboratory at Notre Dame. The chemists gave up working on divinylacetylene and concentrated on the more homely mono-vinylacetylene. They treated it with hydrogen chloride and first thing they knew they had a fine pot of chloroprene. Chloroprene differs from rubber's polymer, isoprene, only in that a chlorine atom replaces the methyl group, so after that the going was fairly easy. They had only to polymerize the chloroprene to the right point, and all of them were experienced polymerizers. When they finished they put a piece of their rubber into a bottle...
...enthusiastic du Pont Co. immediately christened their product Duprene, ordered a plant built at Deepwater, N. J. to manufacture rt commercially. Since it needs only acetylene, salt and water, it will not be expensive to make. Duprene looks like natural rubber, shows the same molecular makeup in xray, but is denser, more resistant to water absorption, to attacks by ozone, oxygen and other chemicals, to swelling by gasoline & kerosene. It is vulcanized by heat alone, without sulphur. At high temperatures it hardens slowly. Its powers of resistance are expected to give it many commercial uses now denied to rubber...
Other commodities to share in the jubilation included rubber, coffee, cocoa, wool tops, hides. Sugar failed to advance, however, and hogs continued in a rut. Mid-Continent oil prices rose 15^ a barrel to 85^; in many sections of the country gasoline was upped...
...Funny man Clark did his best to discard Mr. Arno's inane libretto, inject into the proceedings his own particular brand of in sanity. The simple burlesque business that Mr. Clark knows best consists chiefly in manhandling a cigar, shooting people with a trick cane equipped with a rubber-tube to blow smoke through, ogling all pretty girls through spectacles painted on his face, ranging rapidly about the stage at a half-crouch. All this Mr. Clark has done many times before with success. Bad press notices and the lack of any outstand ing talent other than Clark & McCullough...
