چکیده

Three-dimensional  polymer  based  porous calix[4]resorcinarene  has  many  applications  due  to its special  properties.  The  special  structure  of  this  polymer  and  having  hydroxyl  groups  in  it  can provide the necessary conditions for making derivatives with other functional groups so that we can prepare  other  compounds  with  other  applications.  To  create  functional  groups  and  modify  the surface  of  the  polymer,  silane  coupling  agent  can  be  a  good  option  to  create  new  properties  and effective applications in the porous surfaces of polymer calix[4]resorcinarene. This research intends to provide a simple method for the use of poly(calix[4]resorcinarene) in ultra violet curable organic 
coatings. For this purpose, first the poly(calix[4]resorcinarene) was synthesized and then, by surface modification,  double  carbon-carbon  bonds  were  created  on  it  so  that  we  could  use  it  in  radiant coatings. Then, after characterizing the synthesized materials, the structure and properties have been studied.  The  results  confirmed  the  structure  of  the  synthesized  materials.  Surface  modification improved  the  distribution  of  particles  in  the  polymer  matrix  and  provided  better  coatings  also thermal stability of urethane acrylate resin increased.
