  • Can a 1:1 plasticizer be used for soft PVC products?
  • However, the system with 1:1 plasticizer over PVC had a Tg below 0 °C, indicating that the system was completely flexible at room temperature and could be used for soft (flexible) PVC products. Variation of glass temperature with content of DOP (black stars) and DOP-O-CP52 (red blocks).
  • Do polymeric plasticizers have a low plasticizing efficiency?
  • Unfortunately, they did not try them to PVC. In general, their large molecule size hinders diffusion in PVC to suppress migration. However, the rate of diffusion of the plasticizer is one of the most important factors determining plasticizer efficiency 33, 34. Polymeric plasticizer generally has low plasticizing efficiency.
  • Can phthalate be used as a secondary plasticizer in PVC?
  • In this study, we attached DOP to chlorinated paraffin (CP), acting as a secondary plasticizer in PVC, to prepare a new compound giving PVC highly plasticization without migration. Unlike other reported methods, our approach covalently attaches phthalate to chlorinated paraffin, a low molecular weight compound with a structure similar to PVC.
