The potential biodegradability of several vegetable oil-based polymers was assessed by respirometry in soil for 60-100 days at temperatures of 30-58°C. Films of soybean oil and linseed oil which were oxidatively polymerized (Co catalyst) on a kraft paper support were 90%-100% mineralized to CO2 after 70 days at 30°C. Mineralization of polymerized tung oil to CO2 was much slower than soy or linseed...
