摘　　要：可通过石油树脂的化学及物理改性制备中性施胶剂,马来酸酐与碳五和碳九石油树脂的Diels-Alder反应在200℃左右,加入阳离子分散剂使制得的石油树脂中性施胶剂呈阳离子性,以与其纸纤维结合。实验使用石蜡和复合乳化剂对胶料进行乳化和稳定,同时采用离子型高分子分散剂对石油树脂胶料进行保护。The alkenyl succinic anhydrides sizes was developed by the chemical and physical modification.The addi -tional reaction between the C5～C9components of oil resin with maleic anhydride were carried at high temperature of about 200°C to introduced polar groups and then,the cationic dispersing agent was added on the synthetic resin for the pur pose of connection of cationic siz ing agent with fiber of paper.It is necessary that the synthetic resin sizes were dis persed by the paraffin and emulsified using the complex surfactants.Both the principle of the synthetic reaction and the siz ing mechanism are dis cussed.The present invention relates to emulsions of alkenyl succinic anhydrides and their use to size paper.More particularly,the invention relates to an oil resin sizing emulsion containing low molecular weight and high molecular weight cationic polymers and the use of such an emulsion to size paper.
