Abstract

Controlled reduction of molecular weight of solid-form epoxidised natural rubber (ENR) by a photochemical technique has been studied. The product would be used for preparing rubber-based resin for radiation curing. The technique studied the effects of hydrogen peroxide the rate of molecular weight reduction of the solid as well as its combination with reducing agent such as sodium nitrite. Analysis by IR spectroscopic technique suggest the formation by hydroxyl and carbonyl groups as a result of the ring-opening of the epoxy groups of rubber. NMR as well as IR spectra show the possible formation of furan-like species.

Penurunan terkawal berat molekul getah asli terperoksida (ENR) pepejal dikaji menggunakan teknik fotokimia. Hasil penurunan ini akan digunakan sebagai bahan asas dalam penyediaan resin yang peka kepada sinaran. Dalam kajian ini kesan hidrogen peroksida dan kombinasinya dengan bahan penurun seperti sodium nitrit keatas kadar penurunan berat molekul dikaji. Dari analisis menggunakan IR spektroskopi, dicadangkan berlaku pembentukan kumpulan-kumpulan hidroksil dan karbonil hasil dari pembukaan cincin kumpulan epoksi pada getah. Kedua-dua spektum IR dan NMR menunjukkan kemungkinan terbentuknya spesies berbentuk furan
