1. The polychlorovinyl composition with biomaterial properties contains: a suspension of poly(vinyl chloride), a polymeric and a monomeric plasticizer, a stabilizer, especially a zinc stabilizer and, possibly, lubricants, antioxidants, flow modifiers, anti-blocking compounds and other auxiliary substances. It is characterised in that it contains a mixture of semi-solid polyester-siloxane-urethane oligomer with the molecular weight of at least Mw=1000, preferably between 20 000 and 55 000, which contains 20-80 percent by mass of poly((-caprolacton) blocks and a monomeric plasticiser, preferably di-2-ethylhexyl phthalate. |
