In the furfurylation process, the walls of woody cells are initially swollen with the furfuryl-alcohol-based solution. Due to its polarity and size, furfuryl alcohol penetrates the cell wall. [3] The polymerization of furfuryl alcohol in wood is a complex reaction whose processes are not fully understood.
