Plasticiser loss from plastic or rubber products through
This paper addresses the kinetics and predictions of plasticiser migration from polymers to a surrounding gas phase, an important issue for plastic and rubber products exposed to high service...
Polymers | Special Issue : Green Plasticizers for Polymers - MDPI
Interests: controlled radical polymerization; nitroxide mediated polymerization; green plasticizers Special Issue Information Dear Colleagues, Plasticizers have long been used to impart flexibility and improve the processing behaviour of many polymers, notably poly (vinylchloride) (PVC).

In a two-generational study, two proposed green plasticizers, dioctyl succinate (DOS) and 1,4-butanediol dibenzoate (BDB), were both shown to exhibit no acute toxicity, and DOS also showed no reproductive toxicity, while BDB could produce “subtle but significant alterations of estrogen signaling in the adult testis” [ 34, 66 ].
Developments of biobased plasticizers for compostable
Biobased plasticizers have recently been considered as essential additives, which may be used during the processing of compostable polymers to enormously boost biobased packaging applications. The development and utilization of biobased plasticizers derived from epoxidized soybean oil, castor oil, cardanol, citrate, and isosorbide have been

Plasticizers are typically not covalently bound to the polymers, allowing them to leach out over time, which results in human exposure and environmental contamination. Phthalates, in particular, have been the subject of increasing concern due to their established ubiquity in the environment and their suspected negative health effects, including
- What is the scope of a plasticizer issue?
- The scope of this issue ranges from synthesis of green plasticizers, enhancement of physical and rheological properties, migration of plasticizers upon disposal, relationships between plasticizers and human health, and life-cycle-assessment.
- What are plasticizers used for?
- Plasticizers are additives that are used to impart flexibility to polymer blends and improve their processability. Plasticizers are typically not covalently bound to the polymers, allowing them to leach out over time, which results in human exposure and environmental contamination.
- Does plasticizer species affect free volume properties of poly (vinyl alcohol)?
- The effect of plasticizer species and the degree of hydrolysis (DH) on the free volume properties of poly (vinyl alcohol) (PVA) were studied using positron annihilation lifetime spectroscopy. Both glycerol and propylene glycol caused an increase in the free volume cavity radius, although exhibited [...] Read more.
- How does size affect the performance of plasticizer candidates?
- The performance of the plasticizer candidates improved with increasing size, from the smallest compounds (C2 side chains) to the dihexyl compounds (C6 side chains), and then decreased slightly for the longest molecules (C8 side chains).
- What is epoxidized glycidyl ester of ricinoleic acetic ester?
- A novel renewable plasticizer based on castor oil, epoxidized glycidyl ester of ricinoleic acetic ester (EGERAE), was synthesized and applied into Poly (vinyl chloride) (PVC) for the first time. Its molecular structure was characterized by FT-IR and 1 H NMR. The effects of replacement [...]
- Why are phthalates a problem in plasticizers?
- Despite the improvement in properties in such blends, one the most common group of plasticizers, the phthalates have become increasingly under scrutiny due to concerns regarding toxic metabolites, which can encounter humans via migration from articles, such as blood bags and children’s toys.
