EMULSIFIED LIPOPHILIC PAPER SIZING

摘要

Aqueous emulsions containing lipophilic sizing agents, are used for sizing paper. Volatile nitrogen containing bases, such as ammonium hydroxide and tertiary amines, are used as emulsifying agents to aid in forming aqueous emulsions of lipophilic sizing agents. Preferred lipophilic sizing agents are heterocyclic organic compounds which are formed by the reaction of a dicarboxylic acid anhydride and a long chain hydrocarbon.
