Silane coupling agent is known for the function of combining two materials via the hydrolyzable and organo functional reactive sides (Plueddemann, 1982). Inthepast,the uses of silane coupling agent for the reactive blend between starch and polymers were reported. For example, the compatibility between polyethylene and starch (10wt%) was successful when the starch was pretreated with sodium alkyl siliconate(Griffin, 1994;Wu,Qi,Liang,& Zhang, 2006) demonstrated the improvement of interfacial adhesion between starch and rubber by using resorcinol-formaldehyde and N-(aminoethyl)-aminopropyl trimethoxysilane.
