Current:ENGLISH VERSION > TECHNICAL STRENGTH > Solid State Polymerization-SSP
Project Name:  

  • SSP-Solid State Polymerization (Polytex tech,Polytex Design)
  • Main principle:Solid State Polymerization, also known as solid phase polycondensation, is a polycondensation reaction in a solid state,The polymer chips are heated to a temperature above the glass transition(between about 10-40<C below the melting point),The small molecule is carried away by vacuum or inert gas protection (usually using high purity nitrogen) so that the polycondensation reaction is started and the viscosity is increased.
