Study of the compatibility of plasticizers with poly(vinyl
Dielectric spectroscopy has been applied for studying the compatibility of plasticizers with poly (vinyl chloride) as well as for detecting the phase-inhomogeneities of plasticized systems. Commercial plasticizers having different polarity and compatibility with the polymer have been investigated.
Effects of molecular design parameters on plasticizer
We focus on the effects of plasticizer molecular structure on its performance, as measured by performance metrics including its thermodynamic compatibility with PVC, effectiveness of reducing the material's Young's modulus, and migration rate in the PVC matrix.
Handbook of Plasticizers - 3rd Edition
The book discusses new and historical approaches to the use of plasticizers, explaining mechanisms of plasticizers' action and their behavior in plasticized systems. It goes into detail on the use of plasticizers in a range of specific polymers, polymer blends, and other industrial products.
Environmentally friendly plasticizers for poly(vinyl chloride

- What are the structural features of effective plasticizers?
- Several structural features of effective plasticizers have been recognized. Polar functionality is required to assure compatibility with a wide range of polymeric materials, including poly (vinyl chloride) (PVC), the most heavily plasticized polymer. A branched structure greatly enhances the effectiveness of compounds used as plasticizers.
- What is the role of plasticizers in polymer processing?
- Plasticizers play an important role in polymer processing. This is particularly true for PVC, which may require 40%–60% plasticizer by weight for processing and use . PVC is a polar polymer and, in the absence of plasticization, is a rigid, brittle material .
- Are plasticizers made from biomaterials?
- Some, including those prepared from plant oils, have been generated from biomaterials themselves. However, the more numerous and generally more effective have been generated from discrete compounds produced from various biomaterials. Several structural features of effective plasticizers have been recognized.
- 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 .
- 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.
- Are oligomers a plasticizer?
- An oligomeric structure may strongly limit or prevent migration from a polymer matrix. Hyperbranched oligomers of defined structure derived from the readily-available, inexpensive, nontoxic biomonomers, glycerol and adipic acid contain all these features and are excellent plasticizers.
