Abstract


Telah dilakukan sintesis Linear Low Density Polyethylene- graft-Maleic Anhydride (LLDPE-g-MA) untuk mengetahui pengaruh konsentrasi anhidrida maleat dan peroksida benzoil terhadap persen pencangkokan. Sintesis dilakukan dengan cara mencangkokkan monomer anhidrida maleat ke dalam Linear Low Density Polyethylene (LLDPE) dengan bantuan peroksida benzoil sebagai inisiator dan xylene sebagai pelarut. Reaksi dilakukan dalam reaktor stainless steel pada suhu 120°C selama 5 jam dengan bantuan gas nitrogen. Konsentrasi anhidrida maleat divariasikan antara 10-40 per seratus resin, sedangkan variasi BPO dilakukan pada 0,5-2 per seratus resin. Persen pencangkokan ditentukan dengan menghitung monomer anhidrida maleat yang tercangkok ke dalam LLDPE. Analisis Fourier Transform Infra Red (FTIR) dilakukan untuk mempelajari gugus fungsi yang terbentuk dalam LLDPE-g-MA. Hasil penelitian menunjukkan bahwa persen pencangkokan tertinggi sebesar 9,2598% dihasilkan pada penggunaan anhidrida maleat sebesar 40 per seratus resin dan BPO sebesar 2 per seratus resin.
