摘要
The present invention relates to a PVC product containing cyclodextrin derivative particles and capable of suppressing migration of a plasticizer and a method for manufacturing the same, which includes (S1) preparing cyclodextrin derivative particles, in which a hydroxyl functional group is replaced by a predetermined compound; (S2) inputting the cyclodextrin derivative particles, a water-based dispersion medium and a vinyl chloride monomer into a high-pressure reactor and performing polymerization to obtain cyclodextrin derivative particles-capsulated PVC particles, in which a plurality of the cyclodextrin derivative particles are dispersedly capsulated in PVC particles; and (S3) mixing the cyclodextrin derivative particles-capsulated PVC particles with a low molecular weight liquid plasticizer and molding the mixture in a predetermined shape using heat.
