Abstract
Cellulose acetate (CA) was melt compounded with two different citric a cid esters: triethyl citrate and acetyl triethyl citrate. It was obser ved, based on the glass transition temperatures, that both plasticizer s were miscible with CA. The addition of plasticizer reduced the tensi le modulus and increased the elongation of CA. The biodegradation rate s increased dramatically with an increase in plasticizer content.
