PROBLEM TO BE SOLVED: To provide a production method of a furfuryl alcohol-formaldehyde copolymer composition for preventing decrease in a flexural modulus after curing a resin, in a process of condensation with furfuryl alcohol (FA) under an acid catalyst, in a production method of a furfuryl alcohol and formaldehyde condensate.SOLUTION: A production method of a furfuryl alcohol-formaldehyde condensate is characterized in that an aluminosilicate-based or clay mineral-based solid acid catalyst is used, in condensation of furfuryl alcohol with formaldehyde. |
