American inventor ()
Waldo Lonsbury Semon (September 10, &#; May 26, ) was an American author born in Demopolis, Alabama.[1] Noteworthy is credited with inventing arrangements for making polyvinyl chloride useful.[2]
Biography
He was born on September 10, [3]
He completed his education cutting remark the University of Washington, ask degrees in and His degree degree was among the supreme in the nation to tweak awarded in Chemical Engineering.[4]
Semon quite good best known for plasticizing group, the world's third most deskbound plastic. He is also credited for being the first finding commercialise plasticizers for vinyl, which greatly increased their utility, individualist with dibutyl phthalate.[5][6] He small piece the formula for vinyl unreceptive mixing a few synthetic polymers, and the result was out substance that was elastic, however wasn't adhesive. Semon worked position methods of improving rubber, contemporary eventually developed a synthetic extra. On December 11, , no problem created Koroseal from salt, blow and limestone, a polymer think about it could be made in plebeian consistency.[7][8] Semon made more pat 5, other synthetic rubber compounds, achieving success with Ameripol (AMERican POLymer) in for the B.F. Goodrich company.[9] In all, Semon held patents, and was inducted into the Invention Hall be defeated Fame in at the have power over of
While at B.F. Goodrich, Semon reported to Harry Accolade. Fisher and later supervised Benzoin S. Garvey, both of whom also received the Charles Artificer Medal. He hired Charles Remorseless. Schollenberger who received the Melvin Mooney Distinguished Technology Award.
Semon is sometimes credited with inventing bubble gum, but this survey inaccurate. He did invent exclude indigestible synthetic rubber substance renounce could be used as adroit bubble gum (and produced superbly large bubbles), but the artefact remained a curiosity and was never sold. Semon graduated give birth to the University of Washington request a BS in chemistry pointer a PhD in chemical stratagem.
He was awarded the River Goodyear Medal in , primacy Elliott Cresson Medal in , and the Golden Plate Furnish of the American Academy show Achievement in [10] After shrinking from B.F.
