Title: Akimasa Aoyama: A Legacy of Innovation in Film Technology
Introduction
Akimasa Aoyama was a notable inventor whose contributions to film technology have left a lasting impact. He was based in Kurashiki, Japan, and held a total of 2 patents during his career. His work primarily focused on developing advanced films with exceptional properties.
Latest Patents
Aoyama's latest patents include innovations in polyalcohol film and laminated film. The polyalcohol film features a dynamic modulus of elasticity at 75°C ranging from 10^8 to 10^11 dyne/cm^2 and an oxygen permeability at 20°C, 75% RH of not more than 5×10^12 cc.cm/cm^2.sec.cmHg. This film is made from a polyalcohol obtained by reducing a polyketone, which is a carbon monoxide-ethylene alternate copolymer. The polyalcohol has an intrinsic viscosity of 0.3 to 3.0 dl/g and a melting point between 110°C and 180°C. The laminated film comprising this polyalcohol exhibits excellent high-speed bag formability, heat-pack sealability, film formability, film appearance, adhesiveness, and gas barrier properties. Additionally, he developed a process for producing vinyl acetate polymers, which involves adding a conjugated polyene after the polymerization of vinyl acetate. The saponified products of these polymers yield molded articles with minimal coloring and gel-like agglomerates.
