Lactide-derived ester oligomers for highly compatible poly (lactide) plasticizer produced through an eco-friendly process: renewable resources, biodegradation, enhanced flexibility, and elastomeric performance - Green Chemistry (RSC Publishing) Issue 19, 2025 Previous Article Next Article From the journal: Green Chemistry
Research progress of novel bio-based plasticizers and their
2,5-Dicarboxylic acid ester is derived from biomass resources, but has a structure similar to terephthalic acid ester. As a green chemical, it has the potential to replace petroleum-based plasticizers. Nguyen et al. used raw materials derived from marine biomass to synthesize furan-2,5- and furan-2,3-dicarboxylate as plasticizers for PVC. The
Bioplasticizer - an overview | ScienceDirect Topics
In the mid-1970s, Hercules Chemical Company introduced two polyol ester plasticizers, Hercoflex 600 and Hercoflex 707. These plasticizers were prepared by the esterification of pentaerythritol and dipentaerythritol with a mixture of short-chain acids, predominately C6 acid.
Plasticizers Derived from Biomass Resources: A Short Review.
Hydroxyl and nitrogen rich group-containing tung oil-based ester (GEHTMA-1, GEHTMA-2, GEHTMA-3 and GEHTMA-4) plasticizers are prepared and used to replace dioctyl terephthalate (DOTP) . Figure 17 and Table 1 h,i,j show synthesis route and their chemical structure. GEHTMA-3 displays better mechanical properties and endows PVC resins with well

Particular attention is paid to plasticizers derived from terephthalic acid, which show promise for replacing toxic dioctyl phthalate. The results of studies on synthesis and properties of nonphthalate plasticizers based on benzene, toluene, naphthalene, cyclohexane, and norbornene are considered.
- What is a nonmigrating plasticizer?
- Most prominently, hyperbranched oligomeric esters derived from the readily available, renewable, nontoxic biomonomers, glycerol and adipic acid, are excellent nonmigrating plasticizers. These materials may be produced in a simple process.
- What is an ester plasticizer?
- An ester plasticizer, in its simplest concept, is a high-boiling organic solvent that when added to an elastomeric polymer reduces stiffness and permits easier processing.1 For general performance applications, compounders require moderate performance in several areas without particular emphasis on any one.
- How to choose a high-performance ester plasticizer?
- The rubber compounder must evaluate ester plasticizers for compatibility, processability, permanence and performance properties. The study of these properties by the rubber compounder will contribute to the selection of a high-performance ester plasticizer. 1.

- What is a general performance ester plasticizer?
- Some general performance ester plasticizers used in the marketplace today are DOA, DIDA, DIDP, DOP, DINP and other phthalates and adipates made from straight-chain alcohols of 7–11 carbons in length. Ester plasticizers are commonly used only for their as-molded, low-temperature contribution.
- How can plasticizer toxicity be controlled?
- Plasticizer toxicity may be controlled through the use of abundantly available, renewable, biobased precursors for their generation. Most prominently, hyperbranched oligomeric esters derived from the readily available, renewable, nontoxic biomonomers, glycerol and adipic acid, are excellent nonmigrating plasticizers.
