  • Why is GPC important in PVC characterization?
  • The properties of the final material are dependent on the molecular weight distribution of the PVC and the type and level of the added plasticizers. The analysis of the compounded material is, therefore, of primary importance, and GPC is the ideal analytical tool for its characterization.
  • Are plasticizers a problem in Germany?
  • We found an increasing number of substitutes in the German part of the three major European rivers Rhine, Danube and Elbe, as well as other waters in Germany. As a result, the total burden of plasticizers in the aquatic environment has hardly changed since 2005.
  • Can GC-MS be used for plasticizer analysis?
  • While the use of GC–MS for plasticizer analysis is well known, for example in measuring plasticizer extracted into solvents or food simulants, 6 it has not yet been explored as a way to add quantification to the loop-spew test for exudation. Investigations into plasticizer compatibility also tend towards studying single-plasticizer systems.
  • Why are plasticizers marketed in high volumes?
  • Plasticizers are marketed in high volumes and Di (2-ethylhexyl) phthalate (DEHP) is frequently detected in the environment and human populations. Industry had largely relied on DEHP until regulation started to restrict its marketing in 1999 due to environmental and human health concerns.
  • Can glycerol and diethanolamine be used to plasticize PVA resin?
  • Optimization the plasticizing conditions is one means of addressing this issue. In this study, two types of frequently used plasticizers, glycerol (GLY) and diethanolamine (DEA), are chosen to plasticize PVA resin with a DP of 2400.
  • Can GC-MS detect plasticizer exudation?
  • GC–MS was used to quantify the plasticizer exudation on the surface of plasticised PVC samples stressed as described in the ASTM D3291 compatibility test. This method was able to detect and quantify plasticizer exudation that was not visible by the ASTM D3291 standard method.
