Abstract

The Increasing global energy crisis and scarcity of petroleum resources has shifted the focus of the hemical industries to look for alternative raw material resources. The main focus of raw materials in wood adhesives, such as petroleum and natural gas [1,2], would be gradually replaced by renewable bio-resource polymers. Starch is a relatively an inexpensive and renewable product from abundant plants, easy processing and it has been extensively used as paper binders, sizing materials, glues and pastes [3], but its bonding capacity is not strong enough to glue substrate like wood, paper. Conventionally available wood adhesive emulsions are colloid like polyvinyl alcohol stabilized. A new research on biodegradable, renewable, environmentally friendly starch stabilized polyvinyl acetate emulsion that was synthesized by the graft polymerization of vinyl acetate onto starch. In this paper, we reviewed starch as colloid for synthesis of polyvinyl acetate emulsion.
