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.
