20080200592 | Plasticizer composition containing cyclodextrin derivatives, flexible PVC composition with suppression of the migration of plasticizer containing the same, and manufacturing method thereof - The present invention relates to a plasticizer composition containing cyclodextrin derivatives, a flexible PVC composition with suppression of the migration of plasticizer containing this plasticizer composition, and a manufacturing method of the PVC composition. The manufacturing method includes the steps of: (S1) preparing a cyclodextrin derivative, in which hydrogens of a cyclodextrin are substituted with a certain compound; (S2) mixing the cyclodextrin derivative, PVC and a low molecular weight liquid plasticizer to form a plastisol; and (S3) heating the plastisol into liquid and cooling the plastisol. This manufacturing method uses cyclodextrin derivatives, in which cyclodextrins are modified with certain compounds, and these derivatives form a complex with the low molecular weight liquid plasticizer to suppress plasticizer migration. Thus, this method thereby allows mass-production of the flexible PVC with suppressed plasticizer migration in a simple and economical manner without using a solvent. | 08-21-2008 |
