可聚合非离子型乳化剂稳定的聚丙烯酰胺反相胶乳

Inverse Polyacrylamide Latex Stabilized by Polymerizable Non ionic Emulsifier

近年来，新型可聚合乳化剂的研制及应用引起了人们的极大兴趣［１～４］．目前报道的可聚合乳化剂都是水溶性的，用于正相乳液聚合中改善聚合物膜的性能及聚合物的加工性能［１］，提高聚合物胶乳的稳定性以及制备功能化乳胶粒子等［５，６］．本文合成了油溶性可聚合非离...

The polymerizable non ionic oil soluble emulsifier, acryloyl sorbitan monostearate(ASMS) is synthesized from sorbitan monostearate(SMS) and acryloyl chloride. ASMS shows a greater solubility in some organic solvents than SMS. The inverse latex is prepared from acryl amide and emulsifier in the presence of an initiator. The ASMS stabilized PAM inverse latex has a greater stability than those SMS stabilized latex and its final particle size is controlled by the concentration of ASMS in it. The rheological curves for both the stabilized latexes are presented.
