The effect of styrene monomer in the graft copolymerization of arcylonitrile onto deproteinized natural rubber
Graft copolymerization of an acrylonitrile monomer onto Deproteinized Natural Rubber (DPNR) is an important process in the modification of Natural Rubber (NR) to increase its oil resistance. However, coagulation at the beginning of the process was a problem causing a copolymerization foil to occur. The presence of a styrene monomer...

Pengaruh monomer akrilonitril dan stirena yang dicangkokkan pada karet alam lateks terhadap daya tahan dalam Dimetil Eter (DME) = The Effect of acrylonitrile and styrene monomer grafting onto natural rubber latex on resistance in Dimethyl Ether (DME)
Penelitian ini bertujuan untuk mendapatkan kopolimer cangkok DPNR-g-PAN/PS yang tahan terhadap DME dengan melakukan uji perendaman terhadap DME berdasarkan pengaruh rasio monomer akrilonitril dan stirena. Hasil penelitian menunjukkan bahwa monomer akrilonitril (AN) dapat dicangkokkan pada karet alam dengan stirena (ST) sebagai ko-monomer. Dari karakteristik analisis spektrum dengan FTIR didapatkan gugus...

The effect of temperature increase, holding time and number of layers on ceramic shells using the investment casting process
This study aimed to determine the effect of using acrylonitrile butadiene styrene in place of conventional wax material on treatment pattern removal in the investment casting process. There are three controllable process variables that can affect treatment pattern removal, which include temperature increase, holding time and the number of...
