Determination of adipate plasticizers in poly(vinyl chloride
The optimisation was carried out with pastes of PVC plastified with di-2-ethylhexyl adipate, and extracts were measured by gas chromatography with flame ionization detection. Six different adipate plasticizers were studied, and microwave-assisted extraction was compared with supercritical fluid extraction for the extraction of adipates and
Determination of adipate plasticizers in poly(vinyl chloride
The determination of plasticizers and other additives in plastics is carried out in two steps: (i) sample treatment, in which additives must be separated from the polymer and isolated from other interferent components that are present in plastic matrix; and (ii) measurement, in which additives are measured using a suitable technique.

GC/MS Method for the Determination of Adipate Plasticizers
ABSTRACT: A GC/MS method was developed and successfully validated for the determination of adipate plasticizers in ham sausage migrated from polyvinylidene chloride (PVDC) packaging film. The sample pretreatment includes liquid extraction, solvent evaporation, and reconstitution before and after solid phase extraction (SPE).

- How to evaluate volatilization propensity of plasticizers from PVC synthetic materials?
- Currently, the most commonly employed methods that enable quantitative evaluation of the volatilization propensity of plasticizers from PVC synthetic materials are fogging test and activated carbon method.
- How do we detect plasticizer migration from PVC synthetic materials?
- To this end, this review is compiled as a general review of the methods now available for detecting plasticizer migration from PVC synthetic materials via three different mechanisms (i.e., volatilization, exudation, and extraction), with an emphasis on the instrumentation, methodology, advantages, and limitations of each method.
- How to compare plasticizer volatilization from PVC?
- Thus, some practitioners refer to follow ISO176:2005 (E) that specifies an economically accessible method, intended for a rather rapid comparison of plasticizer volatilization from PVC in the presence of activated carbon. In this method, the PVC synthetic materials are cut into discs of 50 mm ± 1 mm in diameter and 1 mm ± 0.1 mm in thickness.
- What is the molecular weight of poly (butylene adipate)?
- Linear and branched poly (butylene adipate)s (PBA) with molecular weights ranging from 2000 to 10,000 g/mol, and a branching agent content between 0 and 1.8%, were solution cast with poly (vinyl chloride) (PVC) to form 50‐ to 60‐μm thick flexible films.
