ABSTRACT

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 peroxydes;
ii) modification of PhFRs with 1.2-epoxy-3-tert-butylperoxypropane; 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, other funcional groups participate in the network formation.
