Abstract

A composition comprising perfluoro-[2,2]-paracyclophane dimer compound is disclosed. The synthesis reaction of the paracyclophane dimer from 1,4-bis(chlorodifluoromethane)-2,3,5,6-tetrafluorobenzene involves heating in the presence of a metal catalyst and a solvent. A perfluorinated paraxylylene coating formed from the perfluorinated paracyclophane dimer is also disclosed.

Claims

exact text as granted — not AI-modified
1 . A composition comprising perfluoro-[2,2]-paracyclophane represented by the formula,

         3 . (canceled) 
     
     
         4 . (canceled) 
     
     
         5 . (canceled) 
     
     
         6 . (canceled) 
     
     
         7 . (canceled) 
     
     
         8 . (canceled) 
     
     
         9 . (canceled) 
     
     
         10 . (canceled) 
     
     
         11 . (canceled) 
     
     
         12 . (canceled) 
     
     
         13 . (canceled) 
     
     
         14 . A method of coating a surface with a perfluoroparylene coating, comprising:
 polymerizing a perfluoroparacyclophane represented by the formula,   
       
         
           
           
               
               
           
         
       
       on at least a portion of the surface to produce the perfluoroparylene coating represented by the formula,
