Radical polymerizable macrocyclic resin compositions with low polymerization stress

Abstract

A composition of macrocyclic oligomer with at least one polymerizable group, (meth)acrylate, for example.

1 . A composition of macrocyclic oligomer with at least one polymerizable group, (meth)acrylate, for example.  
     
     
         2 . As claimed in  1 , such a polymerizable macrocyclic oligomer was prepared at pseudo high-dilution condition, started from activated precursor.  
     
     
         3 . As claimed in  2 , such an activated precursor could be liquid and/or crystalline solid.  
     
     
         4 . As claimed in  2 , this precursor itself is polymerizable.  
     
     
         5 . As claimed in  2 , various coupling agents such as primary diols, secondary amine or diacids could be used  
     
     
         6 . As claimed in  5 , the moiety could aliphatic or aromatic or both.  
     
     
         7 . As claimed in  2 , the macrocyclic could also be prepared from an activated coupling agent with condensable, polymerizable precursor as well.
