Abstract

A furan polymer impregnated wood which comprises wood impregnated with a polymerizable furfural alcohol monomer solution containing at least water, stabilizers, and furfuryl alcohol, and at least one further compound selected from the group consisting of anhydrides, acids and combinations thereof is described. A method for preparing a furan polymer impregnated wood and uses thereof is also described.

Claims

exact text as granted — not AI-modified
1 . A furan polymer impregnated wood, characterized by wood impregnated with a polymerizable furfural alcohol monomer solution containing at least water, stabilizers, furfuryl alcohol, and one further compound selected from maleic anhydride, phthalic anhydride, maleic acid, malic acid, phthalic acid, and combinations thereof.  
   
   
       2 . The furan polymer impregnated wood of  claim 1 , characterized in that said one further compound is maleic anhydride.  
   
   
       3 . The furan polymer impregnated wood of  claim 1 , characterized in that said one further compound is phthalic anhydride.  
   
   
       4 . The furan polymer impregnated wood of  claim 1 , characterized in that said one further compound is maleic acid.  
   
   
       5 . The furan polymer impregnated wood of  claim 1 , characterized in that said one further compound is malic acid.  
   
   
       6 . The furan polymer impregnated wood of  claim 1 , characterized in that said one further compound is phthalic acid.  
   
   
       7 . The furan polymer impregnated wood of  claim 1 , characterized in that the stabilizers are borax and sodium salts of lignosulfonic acids.  
   
   
       8 - 13 . (canceled)
