CHEMICAL MODIFICATION OF PVC FOR POLYMER MATRICES WITH SPECIAL PROPERTIES

Abstract

Studii recente au relevat faptul ca indeplinirea anumitor condiţii in vederea utilizarii PVC-ului este condiţionata de alegerea unui raport optim intre parţile hidrofila si hidrofoba ale suprafeţei polimerului. Studiul prezent a avut drept scop cresterea procentului hidrofil prin modificari chimice. S-au obţinut derivaţi de PVC care au fost caracterizaţi prin FT-IR, analiza elementala, UV si GPC. S-a demonstrat faptul ca modificarile chimice de suprafaţa ale PVC-ului este metoda optima in vederea schimbarii naturii chimice a suprafeţei pentru utilizarea in aplicaţii speciale. Recent studies have highlighted that the fulfillment of important conditions for PVC use is considered by an optimum ratio between hydrophilic and hydrophobic parts of the polymer surface. The research was conducted with the purpose to increase the hydrophilic part by chemical modifications. PVC-derivatives were obtained, and they were characterized through FT-IR, elemental analysis, UV and GPC. It was demonstrated that chemical modification of PVC proves to be a facile method to change the surface chemical nature, in order to become suitable for the special required applications.
