Abstract

One of the problems associated with this grafting process is the formation of lumps and granules. To overcome this problem, ammonium persulphate ( APS) as catalyst together with amino- metil- propanol (AMP) having 95% purity as neutralizing agent will be used in grafting 25% MA solution with 25% PE solution. To overcome this problem, ammonium persulphate (APS) as catalyst together with the amino-methyl-propanol (AMP) having 95% purity as neutralizing agent. Characterization of the synthesized product includes chemical , bonds identification using Fourier Transform Infra-Red ( FTIR) spectroscopy, viscosity, solid content and softness. The information obtained from FTIR spectroscopy shows that C-O bonds have been replaced by C-N, C=O, C-O bonds and that previously absent N-H bonds are formed. As a whole , this study also shows that PE-g-MA 9% synthesized at 95oC is the most stable solution without the formation of lumps nor separation upon cooling.
