Latest Patents

Wiesner holds a patent for a two-stage hydrolysis process for the preparation of nylon 6. This process involves a first stage conducted at temperatures ranging from about 180°C to 260°C and pressures between 20 to 150 psig for a duration of approximately 0.5 to 4 hours. Before reaching equilibrium conditions, a second stage is initiated at temperatures of about 200°C to 260°C and pressures of about 100-900 Torr for a period of 2 to 15 hours. This method effectively removes most of the water during both hydrolyzation and subsequent polycondensation, ensuring that the cyclic dimer content of the shaped polymer article remains below 0.2 percent by weight. Wiesner's innovative process has resulted in 1 patent.
