Patent ID: 8008375

Claim:
A method for manufacturing poly(vinyl chloride) (PVC) product containing cyclodextrin derivatives with suppression of the migration of plasticizer, the method comprising: (S1) preparing cyclodextrin derivative particles represented by the following Formula 3; (S2) inputting the cyclodextrin derivative particles, a water-based dispersion medium and a vinyl chloride monomer into a 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 any one liquid plasticizer selected from the group consisting of a phthalate plasticizer, an liphatic diester plasticizer, a trimellitate plasticizer and a phosphate plasticizer, and molding the mixture in a predetermined shape using heat: where R each is independently hydrogen, or substituted group of a silane functional group having 1 to 60 carbon atoms, represented by the following Formula 5, and has a degree of substitution of 5 to 100%, and n is an integer of 6 to 26, where a, b, c, d and e each is an integer of at least 0, a+b+c+c+d+e is at least 1, and a linking order between constituent units according to a, b, c, d and e is randomly changed, where R 1 , R 2 and R 3 each is independently the hydrocarbon functional group having 1 to 20 carbon atoms, represented by the Formula 4, and at least one of R 1 , R 2 and R 3 has a vinyl group.
