Emulsification of alkenyl succinic anhydride size

   
   

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.

Os emulsions succinic alkenyl do tamanho do anhydride (ASA) são preparados usando um co-polymer cationic grafted do starch do acrilamido como um agente do emulsification. Os emulsions do tamanho do ASA da invenção atual exibem uma estabilidade significativamente mais grande comparada aos emulsions presentemente disponíveis do tamanho do ASA. O co-polymer grafted do starch é também um agente mais eficiente do emulsification para o tamanho do ASA, permitindo o uso de menos agente do emulsification, conservando desse modo o custo.
