Figure 11.3 shows that the addition of citrate plasticizer decreases the glass transition tem-peramre of the polymer as a result of the plasticizing effect. There is very little difference between the plasticizers - most likely because the plasticizers used in the study had very similar chemical stractures. ... 

Citrate plasticizer n. Any of a family of plasticizers derived from citric acid, HO2C-CH2C(0H)(C02H)CH2C02H, noted for their low order of toxicity. Included citrates are triethyl, tri(2-ethylhexyl), tricyclohexyl, tri-n-butyl, acetyl triethyl, acetyl tri-n-butyl, acetyl tri-n-octyl, n-decyl, and acetyl tri(2-ethylhexyl). 

Nontoxic Citrates Nontoxic citrate plasticizers derived from natural citric acid, such as triethyl citrate (TC), tributyl citrate (TBC), acetyl triethyl citrate (ATC), acetyl tributyl citrate (ATBC), and triacetine, have been shown to be effective plasticizers for PLA [27-29]. Some gas permeability tests have been performed to assess the potential use of PLA and nontoxic citrate plasticizer blends in food packaging and other applications. The effect of ATBC on PLA barrier properties was studied by Coltelli et al. [30] using PLA mixed with ATBC (10-35 wt%), followed by compression molding. Yu et al. [31] blended PLA/ATBC mixmres with carbon black (CB) to form electrically conductive polymer composites. Fourier transform infrared (FTIR) experiments revealed that the interaction between the PLA/ATBC matrix and the CB filler was increased by the addition of ATBC. Water vapor permeability values decreased with an increase in ATBC content (at constant CB levels). For example, at 30wt% CB, the WVP of the PLA decreased from 0.66 x 10 kgm/(msPa) (at 0% ATBC) to 0.10 X 10 kgm/(msPa) with the addition of 30% ATBC.

Cellulose has been identified as a source of biopolymer that can be used as a substitute for petroleum polymers. EPN have been successfully synthesized from cellulose acetate, triethyl citrate plasticizer, and organically modified clay (Misra 2004). The polymer matrix for nanocomposite contains 80 wt% pure cellulose acetate and 20 wt% triethyl citrate plasticizer. Results show that better exfoliated and intercalated structure were obtained from nanocomposites containing 5 and 10 wt% organoclay compared with that of 15 wt% organoclay. Tensile strength of ceUulosic plastic reinforced with 10 wt% organoclay improved by 180 % and thermal stability of the cellulosic plastic also increased.
