Low‐molecular‐weight glycerol esters as plasticizers for poly
Results show that glycerol esters obtained from propanoic, butanoic, isobutanoic, isopentanoic, and benzoic acids, while volatile, can be used as poly (vinyl chloride) plasticizers in certain applications.

Plasticizers Derived from Biomass Resources: A Short Review.
These bio-based plasticizers mainly include epoxidized plasticizer, polyester plasticizer, macromolecular plasticizer, flame retardant plasticizer, citric acid ester plasticizer, glyceryl ester plasticizer and internal plasticizer.
- Is glycerol a nonmigrating plasticizer?
- Branching is most prominent in hyperbranched oligomers, and several have been prepared to function as effective, nonmigrating plasticizers, primarily for PVC [36 38]. Glycerol is a nontoxic, trifunctional biomonomer readily available from biodiesel production and soap making .
- Which polymers are plasticized?
- The plasticizers produced have been applied in 60 polymers and more than 30 groups of products. Industrially, the most common plasticized polymers are PVC, poly (vinyl butyral) (PVB), poly (vinyl acetate) (PVAc), acrylics, cellulose molding compounds, nylon, polyamides and certain copolyamides.
- 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.
- What are natural based plasticizers?
- Nowadays, there is increasing interest in the use of natural-based plasticizers that are characterized by low toxicity and low migration. This group includes epoxidized triglyceride vegetable oils from soybean oil, linseed oil, castor-oil, sunflower oil, and fatty acid esters (FAEs) .
- Are oligomers a good plasticizer?
- An oligomeric structure may strongly limit or pre-vent migration from a polymer matrix. Hyperbranched oligomers of de fined structure derived from the readily-available, inexpensive, nontoxic biomonomers, glycerol and adipic acid contain all these features and are excellent plasticizers.
- What are plasticizers used for?
- Plasticizers are an important class of low molecular weight non-volatile compounds that are widely used in polymer industries as additives . The primary role of such substances is to improve the flexibility and processability of polymers by lowering the second order transition temperature, the glass transition temperature (Tg).
