Procedure

To a 1 liter double walled, oil heated autoclave, having an anchor stirrer 225 g of SMA and 334.4 g of water were added. The SMA had a maleic anhydride content of 26 mole % and a molecular weight of 80.000 g/mole. To this reaction mixture was added 150 g of palm oil (from Cargill, USA) and 40.6 g of a 25% NH3 solution so that the maleic anhydride (MA):NH3 ratio was about 1:1.
