Synthesis and properties of peroxy derivatives of phenol-formaldehyde resins

Methods of obtaining peroxy derivatives of phenol-formaldehyde resins (PhFRs) have been elaborated. Three different procedures have been pursued: i) chemical modification of PhFRs with hydroperoxides: ii) modification of PhFRs with 1.2-epoxy-3-tert-butyl-peroxypropane; and iii) polycondensation of peroxy phenols with formaldehyde. Structures of the resins were determined by chemical and spectroscopic methods. The results: were also used to create three-dimensional networks involving an unsaturated polyester resin. IR-spectroscopy of the networks shows that, in addition to the peroxy groups and unsaturated bonds, others functional groups participate in the network formation.
