Abstract: Biocomposite plate comprises (a) at least one natural fiber, and (b) at least one thermosetting biopolymer comprising a furan resin that is obtainable by polymerizing a composition containing a substituted furan derivative (I) and/or (II). The biocomposite plate exhibits a residual moisture content of less 8 wt.%, based on the total weight of the biocomposite plate. The biocomposite plate comprises at least two sheets of paper. The weight proportion of the biopolymer in the biocomposite plate is at least 20 wt.%, based on the total weight of the biocomposite plate. Biocomposite plate comprises (a) at least one natural fiber, and (b) at least one thermosetting biopolymer comprising a furan resin that is obtainable by polymerizing a composition containing a substituted furan derivative of formula (I) and/or (II). The biocomposite plate exhibits a residual moisture content of less 8 wt.%, based on the total weight of the biocomposite plate. The biocomposite plate comprises at least two sheets of paper. The weight proportion of the biopolymer in the biocomposite plate is at least 20 wt.%, based on the total weight of the biocomposite plate. n : 0-20; t, s : 1-20; w, z : 0 or 1; X, Y1 : O, S or N-R21; R1-R17, R18, R19, R21 : 1-20C alkyl, 2-20C alkenyl, 2-20C alkynyl, 5-24C aryl, 5-12C heteroaryl, carboxaldehyde, OH, hydroxyalkyl, carboxyl, NH 2, NO 2, formyl, alkylamino, aminoalkyl, alkylaminoalkyl, furyl, furyl-alkyl, hydroxyalkylfurylalkyl, alkyloxy, alkoxyalkyl, alkenyloxy, alkylcarbonylalkenyl, oxiranyl, alkylcarbonyloxyalkyl, alkyloxycarbonylalkenyl, alkenylcarbonyloxyalkyl, isocyanate, isocyanate-alkyl, alkylcarboxy, alkenylcarboxy, alkylcarbonyl, alkenylcarbonyl, halocarbonyl, haloalkyl, haloaryl, haloalkenyl, imino, thiol, alkylthio, thioalkyl, alkylthioalkyl, CN, alkylsulfonyl, sulfonic acid (all optionally substituted by 1-20C alkyl, 2-20C alkenyl, 2-20C alkynyl, 5-24C aryl, OH, carboxyl, NO 2, NH 2, furyl, furyl-alkyl, alkyl-furyl, hydroxyalkylfurylalkyl, isocyanate, formyl, halocarbonyl, thiol and/or alkylthio) and/or H; R17 : 1-20C alkyl, 2-20C alkenyl, 2-20C alkynyl, 5-20C aryl, 5-12C heteroaryl, carboxaldehyde, OH, hydroxyalkyl, carboxyl, NH 2, NO 2, formyl, alkylamino, aminoalkyl, alkylaminoalkyl, furyl, furyl-alkyl, hydroxyalkylfurylalkyl, alkyloxy, alkoxyalkyl, alkenyloxy, alkylcarbonylalkenyl, oxiranyl, alkylcarbonyloxyalkyl, alkyloxycarbonylalkenyl, alkenylcarbonyloxyalkyl, isocyanate, isocyanate-alkyl, alkylcarboxy, alkenylcarboxy, alkylcarbonyl, alkenylcarbonyl, halocarbonyl, haloalkyl, haloaryl, haloalkenyl, imino, thiol, alkylthio, thioalkyl, alkylthioalkyl, CN, alkylsulfonyl, sulfonic acid (all optionally substituted by 1-20C alkyl, 2-20C alkenyl, 2-20C alkynyl, 5-24C aryl, OH, carboxyl, NO 2, NH 2, furyl, furyl-alkyl, alkyl-furyl, hydroxyalkylfurylalkyl, isocyanate, formyl, halocarbonyl, thiol and/or alkylthio) and/or H; R20 : 1-20C alkyl, 2-20C alkenyl, 2-20C alkynyl, 5-24C aryl, 5-12C heteroaryl, carboxaldehyde, OH, hydroxyalkyl, carboxyl, NH 2, NO 2, formyl, alkylamino, aminoalkyl, alkylaminoalkyl, furyl, furyl-alkyl, hydroxyalkylfurylalkyl, alkyloxy, alkoxyalkyl, alkenyloxy, alkylcarbonylalkenyl, oxiranyl, alkylcarbonyloxyalkyl, alkyloxycarbonylalkenyl, alkenylcarbonyloxyalkyl, isocyanate, isocyanate-alkyl, alkylcarboxy, alkenylcarboxy, alkylcarbonyl, alkenylcarbonyl, halocarbonyl, haloalkyl, haloaryl, haloalkenyl, imino, thiol, alkylthio, thioalkyl, alkylthioalkyl, CN, alkylsulfonyl and/or sulfonic acid (all optionally substituted by 1-20C alkyl, 2-20C alkenyl, 2-20C alkynyl, 5-24C aryl, OH, carboxyl, NO 2, NH 2, furyl, furyl-alkyl, alkyl-furyl, hydroxyalkylfurylalkyl, isocyanate, formyl, halocarbonyl, thiol and/or alkylthio); and Z : optional double bond.
