Polyphenols with (M) over bar(w)/(M) over bar(n) close to unity were p
repared by polycondensation of tetramethyloyl-derivatives of bisphenol
s with phenols of various structure. The ways to prepare soluble oligo
mers with a yield up to 100% were found. When HCl was used as a cataly
st, polyphenols with molecular mass distribution close to monomodal we
re formed.
