J. Paul Hogan

from Wikipedia, the free encyclopedia

John Paul Hogan (born August 7, 1919 in Lowes (Kentucky) , † February 19, 2012 in Wichita , Kansas ) was an American chemist and inventor.

Life

Hogan studied chemistry and physics at Murray State University in Murray , Kentucky and made his bachelor's degree in 1942. In 1944 he went to the Phillips Petroleum Company in Bartlesville , Oklahoma , where he worked in the research and development department until his retirement in 1985. In 1946 he began working with Robert L. Banks (1921–1989) to manufacture polyolefins . Although Karl Ziegler is considered the founder of catalytic olefin polymerization, because he was the first to publish his results and for which he and Giulio Natta received the Nobel Prize in Chemistry in 1963 , between 1951 and 1953 both Karl Ziegler and Banks and Hogan as well as A. Zletz from the Standard Oil Company has applied for patents for the production of polypropylene under mild conditions (pressures, temperatures) using special metallic catalysts. After lengthy legal disputes, the Phillips company was only awarded the patent for polypropylene in 1983. Hogan and Banks are considered to be its inventors. Their discovery of crystalline polypropylene and the development of a high-density polyethylene (PE) ( high-density PE, PE-HD or HDPE) led Phillips to the industrial manufacture of various products that were marketed under the brand name Marlex .

Hogan was involved in 52 US patents. In 1969 he was honored by the American Chemical Society (ACS) with the Award for Creative Invention . In 1987 he received the Perkin Medal with Robert Banks , and in 1998 they were named Heroes of Chemistry by the ACS.

In 2001 he was inducted into the National Inventors Hall of Fame .
