PENGARUH HIDROGENASI DALAM FASA LATEKS PADA KARET ALAM HEVEA BRASILIENSIS

Abstract

Abstract

Natural Rubber from Hevea brasiliensis  is a polymer with a high content of unsaturated bonds in the molecule, which causes natural rubber to have a low resistance to oxidation, ozone and heat. However the weaknesses of natural rubber may be changed by modification of the molecule of the natural rubber.  This study was done to modify natural rubber with hydrogenation using hidrazine hydrate, hydrogen peroxide and copper sulphate in latex phase. The results show that hydrogenated  rubber has an increased strain, decreased  molecule weight and decreased the Young modulus.

Key words : Hevea brasiliensis, natural rubber, hydrogenation
