Acetyl tributyl citrate (ATBC), effect on adhesion of UV-oured lacquer, 163... 

In another research, Wang et al. [36] investigated the effect of carbon black (CB) on mechanical and thermal properties of plasticized PLA. They used two different plasticizer, acetyl tributyl citrate (ATBC) and poly( 1,3-butylene adipate) (PBA) and revealed the plasticizers improved interaction existed between PLA and CB. The FT-IR spectra revealed that with increasing CB content in each... 

A plasticizer and a compatibilizer are used. As a plasticizer, an epoxidized vegetable oil or esterified and epoxidized vegetable oil is used an amount of 10-50%. Very effective is acetyl tributyl citrate. 

It has to be stressed that some plasticizers which are commonly and successfully used with other polymers, may act as prodegradants for the thermal degradation of PHAs. Glycerol has been reported to act in such a way, while glycerol triacetate (triacetin), although effective as a PHB plasticizer, was found to be inert as a prodegradant [139]. Acetyl tributyl citrate was also examined in this context [140]. 

Additionally, Quero et al studied the isothermal cold-crystallization of PLA/PBAT blends with and without acetyl tributyl citrate (ATBC). SEM results showed that the blends exhibited two phases, but partial miscibility changes in both, Tg and Tn, of the PLA phase, a relationship of the spherulitic growth rate with the blend eomposition and the occlusion of PBAT droplets within PLA spherulites. ATBC acted like a plasticizer for both phases (neat PLA and PBAT). In the ease of blends, ATBC prefers to be included inside the PBAT-rieh phase. There was a synergistic effect on the overall crystallization rate of PLA when both ATBC and PBAT were present in the blend.

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. 

Badeka and Kontominas [30] studied the effect of microwave heating on the migration of dodecyl adipate and acetyl tributyl citrate plasticisers from food grade PVC into olive oil.
