ALEXANDRIA, Va., Sept. 30 -- United States Patent no. 12,747,345, issued on Sept. 29, was assigned to MITSUBISHI CHEMICAL Corp. (Tokyo).
"Ethylene-vinyl alcohol copolymer composition" was invented by Kota Inoue (Tokyo) and Daichi Morita (Tokyo).
According to the abstract* released by the U.S. Patent & Trademark Office: "An ethylene-vinyl alcohol copolymer composition that contains an ethylene-vinyl alcohol copolymer (A), an unmodified polyolefin (B), and an acid-modified polyolefin (C). The mass ratio [(B)/(C)] between the unmodified polyolefin (B) and the acid-modified polyolefin (C) is 75/25 to 1/99. The melt viscosity ratio [(Eta1)/(Eta2)] between the melt viscosity (Eta1) of the composition at 210deg C. and a shear rate of 18 (sec-1) ...
