Notizen:
Poly(p-hydroxycinnamic acid) was synthesized by thionyl chloride activated polycondensation of p-hydroxycinnamic acid at ambient temperatures and by polycondensation of its various monomeric esters at elevated temperatures. The thionyl chloride activated polycondensation proceeds as a 2-stage process, yielding reduced viscosities of up to 102 mL/g. 360 MHz proton NMR spectra indicate an all-trans structure and the absence of side reactions. The polymer with a melting temperature of 313°C can be pressed into films.
