摘要：NOVELTY - The invention relates to an anion low-polymer surface activator and relative preparing method. Wherein, said surface activator has the structure as (1). And said preparing method comprises: first processing ring-opening additive reaction between glycerin glycidic alcohol and primary amine to attain ring-opening adduct; than reacting the ring-opening adduct with SOCI2 or Cl3OH2 SOCl2 to attaint theproduct in alkali condition. And the final product has better surface activity with simple preparation and wider material supply. Wherein, the (1) means: R1 is C10-C16 alkyl; R2 is SO3H, SO3M, or ; Mis K or Na.
