Nonmigrating Equivalent Substitutes for PVC/DOP Formulations
Hydrophilic oligomers (containing predominantly EO) of molecular weights between 2000 and 5000 g mol 1 exhibit excellent plasticizer efficiency, nearly identical to di‐2‐ethylhexylphthalate (DOP) in conventional PVC/DOP mixtures and may therefore be used as nonmigrating equivalents for DOP.

- 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.
- 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.
- Why is DOP a good plasticizer for PVC?
- High plasticizing efficiency of DOP for PVC is attributed to DOP’s good compatibility with PVC and its high rate of diffusion in PVC, which result from the interaction between DOP and PVC molecules.
- Can chlorinated paraffin be used as a secondary plasticizer?
- Although it has limited compatibility with PVC, chlorinated paraffin as a secondary plasticizer may have a stronger interaction with PVC than other secondary plasticizers because it has a chemical structure similar to PVC. In this study, DOP and chlorinated paraffin were chemically combined into a new compound, DOP-O-CP52.
- Is DOP-o-cp52 a better plasticizer than DOP?
- Both Tgs were gradually reduced with the increased addition of plasticizer. DOP-O-CP52 has almost the same plasticizing efficiency as DOP within the ratio range (from 0 to 0.3) of plasticizer to PVC, which indicated the novel DOP-like plasticizer could have the same performance as DOP in many applications.
- Is cp52 a good plasticizer for PVC?
- However, stronger interactions between plasticizer and PVC will reduce its rate of diffusion in PVC, leading to lower plasticizing efficiency. A compromise is achieved using DOP-O-CP52, yielding PVC with no migration and high plasticization. CP52 appears to be a better choice for DOP.
