The Preparation of Starch Sodium Octenyl Succinate and its Application as Surface Sizing Agent

Abstract:

The preparation of Starch sodium octenyl Succinate (SSOS) and its application as a surface sizing agent in papermaking was studied in this paper. The effect of different reaction conditions on esterification of starch was firstly discussed. Based on which, SSOS with different degree of substitution (DS) was obtained and its surface sizing performance was researched. The results showed that the optimal esterification conditions were as follows: When pH is 8.5, reaction emperature is 35°C, reaction time is 3h, the maximum reaction efficiency can be achieved. The study of surface sizing performance of SSOS showed that when solid content of SSOS was 0.8613 and its DS was 0.0381, the picking speed of paper was up to a maximum value. SSOS showed a good film-forming property when its concentration was 3%.
