Patent ID: 7008984

Claim:
A method for preparing furan polymer impregnated wood, comprising impregnating wood in one impregnation step with a polymerizable furfuryl alcohol monomer solution, said solution containing, based on the weight of the solution, from 4.8 to 33.3% of furfuryl alcohol, from 1.9 to 5.1% of borax, from 1.9 to 5.1% of maleic anhydride or maleic acid or a combination thereof as a polymerization initiator for the polymerization of the furfuryl alcohol, and the balance water and curing the impregnated wood at a temperature in a range of from about 70 to about 140° C. to form furan polymer impregnated wood having a furan polymer content of from 6.3 to 48.3% based on the weight of the wood.
