Abstract Natural hydrolysable chestnut tannin extracts used to partially substitute phenol in Phenol-Formaldehyde
(PF) resins for phenolic rigid foams were analysed by matrix-assisted desorption ionization time of fl ight (MALDI-TOF)
mass spectrometry. PF only, chestnut only and PF-chestnut copolymerised oligomer types and distribution were determined.
MALDI-TOF analyses of a PF control resin (with the same molar ratio) and of chestnut tannin extracts were performed
in order to identify the peaks of molecular weights corresponding to copolymers of chestnut tannins with phenol and
formaldehyde. More >
