    • A process for the treatment of wooden elements, said process comprising the following steps: conditioning said wooden elements to reduce their moisture content; and a) performing one of the following sequences of steps selected from the group consisting of at least the sequence of steps b1) to b4) or at least the sequence of steps bb1) to bb2); said sequence of step b1) to b4) at least comprising: b1) impregnating the wooden elements obtained from step a) with at least one wood preservative, b2) heating the wooden elements obtained from step b1) at a temperature of at least 51° C to fix said wood preservative(s) in said wooden elements, b3) impregnating the wooden elements obtained from step b2) with a solution comprising polymerizable reactive groups, identical or different, that can form a polymer under polymerizing condition, and b4) subjecting the wooden elements obtained from step b3) to polymerizing condition to polymerize said reactive group(s); said sequence of steps bb1) to bb2) at least comprising: bb1) impregnating the wooden elements obtained from step a) with a mixture of at least one wood preservative and polymerizable reactive groups, identical or different, that can form a polymer under polymerizing condition, and bb1) heating the wooden elements obtained from step bb2) at a temperature of at least 51°C to fix the wood preservative(s) and to polymerize said reactive groups. The treated wooden elements so obtained and their uses.
    • 一种用于处理木质元素的方法,所述方法包括以下步骤:调节所述木质元素以减少其含水量; 和a)执行以下选自由至少步骤b1)至b4的序列组成的组中的步骤之一或至少步骤bb1至bb2的序列); 步骤b1)至b4)的顺序至少包括:b1)用至少一种木材防腐剂浸渍由步骤a)获得的木质元素,b2)在至少51℃的温度下加热由步骤b1)获得的木质元素 C将所述木质部件中的所述木材防腐剂固定在所述木质部件中,b3)用包含在聚合条件下可形成聚合物的相同或不同的可聚合反应性基团的溶液浸渍由步骤b2)获得的木质元素,以及b4) 从步骤b3)获得的木质元素聚合到聚合所述反应性基团的条件下; 所述步骤bb1)至bb2)的步骤至少包括:bb1)使用可在聚合条件下形成聚合物的相同或不同的至少一种木材防腐剂和可聚合的反应性基团的混合物浸渍由步骤a)获得的木质元素 和bb1)在至少51℃的温度下加热从步骤bb2获得的木质元素)以固定木材防腐剂并聚合所述反应性基团。 经过处理的木质元素如此获得及其用途。
