PLASTICIZER COMPOSITION CONTAINING CYCLODEXTRIN DERIVATIVES, FLEXIBLE PVC COMPOSITION WITH SUPPRESSION OF THE MIGRATION OF PLASTICIZER CONTAINING THE SAME, AND MANUFACTURING METHOD THEREOF |
摘要 |
<p>Disclosed are plasticizer compositions including cyclodextrin derivatives, a flexible PVC composition with suppression of the migration of a plasticizer containing the same, and a manufacturing method thereof. The manufacturing method of the flexible PVC composition of the present invention includes steps of (Sl) preparing cyclodextrin derivatives; (S2) mixing the cyclodextrin derivatives, PVC and a low molecular weight liquid plasticizer to form a plastisol; and (S3) heating the plastisol to form a solution and cooling the solution. The manufacturing method of the present invention may be useful to mass-produce flexible PVC with suppression of the migration of a plasticizer in a simple and economic manner without using solvents since the cyclodextrin derivatives are used as a compound that can suppress the migration of a plasticizer. The flexible PVC has an effect of reducing an amount of the migrated plasticizer without deterioration in its physical properties.</p> |
