In 1933, he was issued the first American patent (USP 1897977) for an unsaturated
polyester, followed by a patent for polyester co-polymers in the year before his death (USP 2195362). Ellis died of
influenza at the age of 64, while vacationing at
Miami Beach. A
merchant marine tanker, the
Liberty ship S.S.
Carleton Ellis, was later named in his honor during
World War II.
Time magazine eulogized him by writing, "Chemist Ellis' inventions gave birth to more than 100,000 compounds. He developed
Standard Oil's tube-&-tank process of cracking oil, found the formula for cheap
acetone to fireproof airplane wings in
World War I, and made plastics an exact and lucrative science." He was awarded the
Edward Longstreth Medal in 1916. He was inducted into the Plastics Hall of Fame in 1974. ==Publications==
