When modification graft before emulsiondispersion in solvent was adopted, micro phase separation of soft and hard segments in molecular chains was enhanced greatly and its thermo-stability improved .
而采用在溶剂相中改性接枝再乳化分散的方式，分子链中软硬段的微相分离加剧，热稳定性提高。

CMC can form a stable emulsion with vinegar, soy sauce, vegetable oil, fruit juice, vegetable juice, gravy, dispersion, its dosage is 0. 2% to 5%.
This paper focuses on the preparation of the polymeric emulsifier for AKD emulsion, which is significant in dispersion, emulsifying and stabilization for its special construction unit.
