ABSTRACT OF THE DISCLOSURE Finished articles made of flexible PVC using the plastisol technology are improved in terms of resistance to heat and solvents, and of 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.
