STUDY OF THE EFFECT OF SOLVENT AND QUANTITY OF CATALYST ON ARICRYL POLYMERIZATION AT PT. ARISTEK HIGHPOLYMER BEKASI

Aricryl synthesis was carried out by feeding technique. The monomers used were styrene, isobutyl acrylate, 2-HEMA and acrylamide powder. The catalysts used were AIBN (Azobisisobutyronitrile) and Perbutyl O98. The synthesis results were then devided by 2 for resin batch G-0915 A was diluted in > 63% mixture of n-butanol and methanol, while for G-0915 B was carried out dilution in > 63% toluene. the results obtained were compared based on the influence of the solvent using the parameters of viscosity, NV/total solid, AV (Acid Value), color and OH value. It was found that the best solvent according to specifications is toluene solvent with a viscosity of Z2-15. The Aricryl batch G-0915 was compared with Aricryl batch G-0903 based on the influence of the quantity of catalyst. The results showed that the increasing quantity of catalyst affects the aging process. Aging duration for Aricryl batch G-0903 was 11 hours, while for Arycril batch G-0915 was 8 hours.
