Abstract
Alkenyl succinic anhydride (ASA) size emulsions are prepared using a grafted cationic acrylamide starch co-polymer as an emulsification agent. The ASA size emulsions of the present invention exhibit significantly greater stability compared to presently available ASA size emulsions. The grafted starch co-polymer also is a more efficient emulsification agent for ASA size, permitting the use of less emulsification agent, thereby saving cost.
Claims9
A process of emulsifying alkenyl anhydride size comprising blending an alkenyl succinic anhydride and a starch grafted calionic acrylmide co-polymer under conditions sufficient to form an emulsion, wherein said grafted cationic co-polymer comprises a reaction product of starch, acrylamide, and a diallyldialkyl ammonium halide.
