Pencangkokan Anhidrida Maleat Pada Karet Alam Siklis : Penambahan Divinil Benzen untuk Meningkatkan Derajat Pencangkokan

Abstract: Derajat pencangkokan anhidrida maleat pada karet alam siklis secara umum masih rendah, yang disebabkan kurangnya densitas elektron ikatan rangkap anhidrida maleat sehingga reaktifitasnya rendah. Penelitian ini bertujuan untuk meningkatkan derajat pencangkokan dengan penambahan komonomer divinil benzen. Pada penelitian ini dilakukan penambahan anhidrida maleat 2, 4, 8 dan 16 phr dengan dan tanpa komonomer divinil benzen di dalam pencampur internal suhu 150 o C dan kecepatan rotor 80 rpm. Untuk mempelajari penga… Show more

“…Modification of CNR by grafting using Maleic Anhydride (AM) monomer has been successfully carried out by several researchers (Zhao et al 2018;Ritonga et al 2019). Based on the Fourier Transformed Infra-Red/FTIR spectral data of the grafted product, the maleate group was successfully grafted onto the CNR structure with the appearance of absorption at 1780 cm-1 and 1841 cm-1 which is a typical carbonyl absorption of the maleate group (Sitanggang & Eddyanto, 2019;Eddiyanto, 2007;Siregar et al 2014;Siregar, 2015;Siregar et al 2019;Siregar et al 2021a;Siregar et al 2021b). To increase the degree of grafting, styrene comonomers (Siregar et al 2014), divinylbenzene (Siregar et al 2019;Siregar et al 2021a;Siregar et al 2021b) and Trimethylol Propane Triacrylate (Siregar et al 2019;Siregar et al 2021) have been used.…”
