Finished articles made of flexible PVC using the plastisol technology having a high resistance to heat and solvents, and a reduction in plasticizer migration by incorporating into the traditional plastisol ingredients, appropriate amounts of di- or polyisocyanates and di- or polyols, and/or di- or polyamines, which, upon heating, copolymerize with one another while the PVC is gelling, to form a polymer network within the article. |
