Abstract
Obiectul prezenteiinventii îl constituie o compozitie pe baza de policlorura de vinil, utilizata în medicina pentru un contact de lunga durata cu sangele, caracterizata printr-un indice scazut de migrare a compusilor cu molecule mici catre extracte de apa, concomitent cu capacitatea unei desorbtii rapide si complete a aburului absorbit în timpul sterilizarii în abur. Scaderea inducelui de migrare si cresterea vitezei desorbtiei aburului se atinge prin adaugarerea unui antioxidant din grupa trialchilfenolilor, într-o cantitate de 0,05..0,15% în greutate, calculate în raport cu plastifiantul. Materialul conform inventiei se obtine prin amestecarea si omogenizarea în amestecator fluidal a urmatoarelor componente: suspensie de policlorura de vinil, di-2-etilhexilftalat, ulei de soia expoxiat, sterat de calciu si zinc si antioxidantul. Din amestecul uscat astfel preparat se extrudeaza un granulat, care este apoi prelucrat dupa metode cunoscute.
