When the surfaces of flexible PVC sheets were similarly modified, we found that plasticizer migration could be prevented completely, as it was in PVC tubes. How-ever, modification led

Flexible samples with 0.32:1 plasticizer over PVC were selected to ensure a high migration rate of plasticizers. These results indicated that the new DOP-like plasticizer in PVC was very stable.

Why is plasticizer important?
Plasticizer is not only a processing aid but also an important component to determine the performance and application of PVC. Therefore, plasticizers are the most important commercial application of PVC. However, plasticizers can leach out of flexible PVC, changing the performance of PVC with age and contaminating the environment.
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).
Which plasticizer has a low plasticizing efficiency?
Polymeric plasticizer generally has low plasticizing efficiency. Navarro et al. 35 replaced the chlorine on the PVC backbone via nucleophilic substitution of thiol groups attached to the benzene ring of di (2-ethylhexyl)phthalate (also known as dioctyl phthalate, DOP, the most common plasticizer), to give totally nonleachable PVC.
What is nonmigrating highly plasticized PVC?
Nonmigrating highly plasticized PVC was prepared based on a new compound that acts as a plasticizer that was derived from di (2-ethylhexyl) 4-hydrophthalate and chlorinated paraffin-52. The as-prepared PVC has a plasticizing efficiency as high as DOP and its migration is totally suppressed.
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.
Is PVC a plasticizer?
The low molecular weight compound was defined as a plasticizer by The Council of the International Union of Pure and Applied Chemistry. Internally plasticized PVC can maintain its performance over long-term use because there is no plasticizer migration.
