                 Abstract: A self-emulsification microemulsion method was used to prepare an amphiphilic water-soluble
                 polymer  using  acrylamide  (AM),  acrylic  acid  (AA)  and  styrene  (St)  as  raw  materials.  This  preparation
                 method avoids the problem  that too many small  molecule emulsifiers are introduced into the traditional
                 microemulsion  polymerization,  which  leads  to  the  complex  post-processing  process.  In  addition,  the
                                                                                           1
                 mechanism  of  self-emulsified  microemulsion  polymerization  was  discussed.  FTIR  and  HNMR  results
                 showed that the copolymerization of AM, AA and St was carried out. The DSC result revealed that the
                 obtained  copolymer  was  a  block  structure.  The  results  of  the  surface  tension  tester  and  the  numerical
                 viscosity test showed that when m(AM) : m(AA) : m(St) was 87.5 : 10.0 : 2.5, the surface tension and viscosity
                 of  the  prepared  copolymer  solution  were  26.113  mN/m  and  1260  mPa·s,  respectively.  Furthermore,  the
                 molecular  chain  aggregation  state  of  the  copolymer  with  different  content  of  hydrophobic  monomer  in
                 solution was explained.
