Synthesis of novel plasticizer ester end-capped oligomeric
Furthermore, compared with ATBC and DOTP, EOLs showed better migration resistance in the leaching test. All test results showed that the comprehensive performance of EOLs was better than those of commercial green plasticizers ATBC and DOTP, which provided a new method for the development of novel green plasticizers.
Ester Plasticizers for Polyvinyl Chloride - Springer
low extractability with water, oils, and detergents, good compatibility with the polymer, low volatility, chemical stability, plasticizing performance, nontoxicity, and low cost [1, 2]. Organic compounds of different classes can be used as plasticizers: esters of dicarboxylic and phosphoric ac-

Bis(2-ethylhexyl) terephthalate
One method of manufacture entails the transesterification of dimethyl terephthalate with 2-ethylhexanol : C 6 H 4 (CO) 2 (OCH 3) 2 + 2 C 8 H 17 OH → C 6 H 4 (CO 2 C 8 H 17) 2 + 2CH 3 OH A second method of manufacture is a direct esterification of terephthalic acid with 2-ethylhexanol :
US6310235B1 - Method for producing ester plasticizers
The invention relates to an improved method for producing ester plasticizers by reacting di- or polycarboxylic acids or their anhydrides with alcohols in the presence of metal catalysts. Description This application is a 371 of PCT/EP98/02899 filed May 16, 1998.
- Can adipic acid ester be used as a PVC plasticizer?
- The purpose of this work is the synthesis of adipic acid ester and the study of the possibility of its use as a PVC plasticizer. The resulting butyl phenoxyethyl adipate was characterized by Fourier-transform infrared spectrometry, thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC).
- How effective is a plasticizer in reducing glass-transition temperature?
- A decrease in the glass-transition temperature with the introduction of a plasticizer is an important criterion for assessing the effectiveness of its plasticizing action. The results shown in Table 2 show that the sample of unplasticized polyvinyl chloride corresponds to Tgt = 87.5 °C.
- Which plasticizer is used in conjunction with low-molecular-weight plasticizer?
- As a rule, they are used in conjunction with small amounts of low-molecular-weight plasticizer. Known plasticizer based on castor oil, which is gradually hydrogenated, esterified and acetylated to obtain triacetylated monoglyceride ester.
- Is adipate a good plasticizer?
- The new environmentally friendly plasticizer has good compatibility with PVC and high thermal stability. The effectiveness of the plasticizing action of adipate based on the glass-transition temperature was 132.2 °C in relation to pure PVC and 7.7 °C in comparison to compounds based on DOP.
- What is a plasticizer based on castor oil?
- Known plasticizer based on castor oil, which is gradually hydrogenated, esterified and acetylated to obtain triacetylated monoglyceride ester. The disadvantage of using castor oil as a feedstock is that products based on it are more expensive than phthalates, and the world supply of castor oil is limited [ 51 ].
- How does a new plasticizer work?
- Thus, studies have shown that the new plasticizer is characterized by high technological indicators—the thermal stability and efficiency of the plasticizing action—and also contributes to an increase in the fluidity of the melt of polymer compositions and the expansion of the temperature range for processing compounds based on it.
