The internal plasticization of PVC by displacement of chlorine with phthalate-based thiol additives, that is, the covalent attachment of the plasticizer to the PVC chain, is described for the first time. Using this methodology, a
analyzed. Data on new esteri fi cation catalysts are presented. Particular attention is paid to plasticizers derived from terephthalic acid, which show promise for replacing toxic dioctyl phthalate. The results of studies on synthesis and concerning the synthesis of ester plasticizers for PVC and demonstrating the main trends in the modern
- 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.
- How does cp52 affect plasticization efficiency?
- With higher DOP-O-CP52 levels in PVC, CP52 in DOP-O-CP52 will form microclusters owing to their lower compatibility with PVC, to retard the movement of DOP-O-CP52 in PVC, resulting in a decline in plasticizing efficiency. Figure 6 shown the extraction of plasticized PVCs.
- What is internal plasticization of PVC?
- The internal plasticization of PVC by displacement of chlorine with phthalate-based thiol additives, that is, the covalent attachment of the plasticizer to the PVC chain, is described for the first time.
- 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.
- Does phthalate-free self-plasticization of poly (vinyl chloride) conform to green chemistry?
- The phthalate-free self-plasticization of poly (vinyl chloride) (PVC) conforms to the concept of green chemistry. In this work, phthalate-free, biocontaining, self-plasticized PVC with nonmigration ...
- 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.
